I'm a total newbie at flash.
I'm on flash CS6, and action script 2.0.
What I'm trying to do, is make it so that when a movie clip (bird_mc) collides with
another movie clip (missile_mc), then the movie jumps to a later frame.
My script below doesn't include missile_mc, and this is surely a problem, so how do
I get these two movie clips to when touch move the movie to another frame?
The bird_mc has action script to move up and down with the up and down arrow keys, and
the action script below is connected to frame 1.
Please help, I have no idea what is required to make this work, as I am a beginner!
My action script may be all completely wrong, so anything new or any edition of mine
is great.
Here is the action script on frame 1:
if (_root.bird_mc.hitTest(_x, _y, true)) {
_root.gotoAndStop(2);
}
If your movieClips and your actionScript code are all in frame 1:
this.onEnterFrame = function():Void {
if (bird_mc.hitTest(missile_mc._x, missile_mc._y, true)) {
gotoAndStop(2);
}
}
If you put your code within the movieclip missile_mc:
this.onEnterFrame = function():Void {
if (_parent.bird_mc.hitTest(_x, _y, true)) {
_parent.gotoAndStop(2);
}
}

I have a code to when I press "p" the game pauses. Although, I want to show some text saying like "Game is Paused. Press P to progress" how can I do that? Here´s my code:
//create event
pause=false;
pauseSurf=-1;
pauseSurfBuffer=-1;
resW=1920;
resH=1080;
//Post-Draw event
gpu_set_blendenable(false);
if(pause)
{
surface_set_target(application_surface);
if(surface_exists(pauseSurf)) draw_surface(pauseSurf,0,0);
else // restore from buffer if we lost the surface
{
pauseSurf = surface_create(resW,resH);
buffer_set_surface(pauseSurfBuffer,pauseSurf,0);
}
surface_reset_target();
}
if(keyboard_check_pressed(ord("P")))// Toggle pause(Whatever condition/trigger you like)
{
if(!pause)// pause now
{
pause=true;
// deactivate everything other than this instance
instance_deactivate_all(true);
// NOTE:
// If you need to pause anything like animating sprites,tiles,room backgrounds
// you need to do that separately,unfortunately!
// capture this game moment(won't capture draw gui contents though)
pauseSurf=surface_create(resW,resH);
surface_set_target(pauseSurf);
draw_surface(application_surface,0,0);
surface_reset_target();
// Back up this surface toabuffer in case we lose it(screen focus,etc)
if(buffer_exists(pauseSurfBuffer)) buffer_delete(pauseSurfBuffer);
pauseSurfBuffer=buffer_create(resW*resH*4,buffer_fixed,1);
buffer_get_surface(pauseSurfBuffer,pauseSurf,0);
}
else // unpause now
{
pause=false;
instance_activate_all();
if(surface_exists(pauseSurf))surface_free(pauseSurf);
if(buffer_exists(pauseSurfBuffer))buffer_delete(pauseSurfBuffer);
}
}
gpu_set_blendenable(true);
//Clean up event
if(surface_exists(pauseSurf))surface_free(pauseSurf);
if(buffer_exists(pauseSurfBuffer))buffer_delete(pauseSurfBuffer);

If any of you knows how to help me I would be thankful! :)
Add a DrawGui Event to your object, and then add the following code within:
if (pause)
{
draw_text(50, 50, "Game is Paused. Press P to progress");
}
DrawGui makes it so that it renders on top of your viewport, so it's not connected with the position in the room.
The 50, 50, is the X and Y position of the text, use it as you see fit. You can use it centered if you take the width/height of the camera/viewport and divide that by 2.
The pause is already defined in the Create Event, so that shouldn't give any problems.
I'm new here!
I searched internet a lot for my question, but I didn't found anything - or I'm really thinking wrong.
I program on VB.NET since 2 years, and on XNA since 6 months. I built a game and an editor for the game, and they are running great.
The question i about my editor (for an RPG game), and I'll try to explain at my best.
I have a main form with menustrips on top and a big picturebox covering the entire form, a picbox that is binded to the Game1 object when it start with the command Run().
The Game1 object handles two classes, that are basically panels that it draws on the picbox of the main form: a tileset panel in the left down the tabpage, and a map panel on the right. This works perfectly.
The problem is when for the first time yesterday I tried to draw with XNA on a form. I have multiple forms to manage NPCs, equipment, conditions, events, variables, etc and in the event form, I have a tabpage that manages map teleport events. On this tabpage I have a list of maps and a picbox where I want to draw a small view of the selected map. For this, I created of course a minimap panel with it's own draw and update methods.
...but of course, the minimap appears on the main form on the normal map.
I tried to change in real time the DeviceWindowHandle, but I failed... apparently, it changes only during the Run()
I tried to create a new game object and binding him to the event teleport form, but in the moment of lunching the Run() of this object, the debugger stops saying that I cannot launch more that one game loop in a thread.
I can't believe that XNA doesn't let to draw multiple things on different forms... and I can not pause the main loop from the event form (which is called from the NPC form) to start the minimap loop!
I think that is something really easy that unfortunately I don't know...
I'm getting crazy and lost... what I can do?
Please help me, thanks!!
Here's an example of what I commented (Sorry it's in C# but I don't really write VB.Net. Translating it should be pretty straight forward though):
private MainGame mainGame;
private ToolboxGame toolbox1;
private ToolboxGame toolbox2;
// And this should be put in some Form Initialization method:
Task.Factory.StartNew(() => {
this.mainGame = new MainGame(imgEditorPictureBox.Handle)
this.mainGame.Run();
}
Task.Factory.StartNew(() => {
this.toolbox1 = new ToolboxGame(toolbox1PictureBox.Handle)
this.toolbox1.Run();
}
Task.Factory.StartNew(() => {
this.toolbox2 = new ToolboxGame(toolbox2PictureBox.Handle)
this.toolbox2.Run();
}
Something like that should do it. Obviously whenever you "move" variables from one "game" to another, keep in mind that they run on different threads, so anywhere you use it, you'll need to
lock (dummyObject)
{
// Use data
}
to make sure you're not accessing it in one game, while the other is trying to set it.
Locking in VB.Net: Is there a lock statement in VB.NET?
You'll obviously need to come up with some smart infrastructure to get this working smoothly, but since you've made a game and editor before, I'm sure this should not prove a humongous challenge.
All you want show to the player you need draw in the game window. You have one Game with one GraphicsDevice and by default all you draw will be rendered on the game window. But you can call GraphicsDevice.SetRenderTarget method to change render target. Call it with RenderTarget2D object as parameter and anithing you will draw after this will be rendered to that render target.
Next you need call GraphicsDevice.SetRenderTarget(null) to set game window as render target again.
There is my (uncompleted yet) custom GUI realization for XNA. I hope it can help you.
Update
class Game1 : Game
{
GraphicsDevice graphicsDevice;
SpriteBatch spriteBatch;
public RenderTarget2D MinimapRenderBuffer;
public RenderTarget2D AnotherRenderBuffer1;
public RenderTarget2D AnotherRenderBuffer2;
public EventHandler RenderBuffersUpdated;
void Initialize()
{
// Better initialize them only once, don't do it in Draw method
this.MinimapRenderBuffer = new RenderTarget2D(this.graphicsDevice, 100, 100); // any size you want
this.AnotherRenderBuffer1 = new RenderTarget2D(this.graphicsDevice, 50, 50);
this.AnotherRenderBuffer2 = new RenderTarget2D(this.graphicsDevice, 500, 500);
}
void Draw()
{
this.graphicsDevice.SetRenderTarget(this.MinimapRenderBuffer);
// draw minimap to MinimapRenderBuffer
this.graphicsDevice.SetRenderTarget(this.AnotherRenderBuffer1);
// draw whatewer to AnotherRenderBuffer1
this.graphicsDevice.SetRenderTarget(this.AnotherRenderBuffer2);
// draw whatewer to AnotherRenderBuffer2
this.graphicsDevice.SetRenderTarget(null);
// now draw to screen
if (this.RenderBuffersUpdated != null)
{
RenderBuffersUpdated(null, null);
}
}
}
And use rendertargets in your editor when event raised. And you can convert them to bitmaps.
I am looking for the instructions of how to make an preloader using GCD, but no luck for now. I would like to learn how to preload all the textures and emitters in the background, before scene is initialized. And if possible, update the progress bar animation based on amount of data loaded.
I am looking at Apple's adventure game, and there is an example for similar problem. Actually, the first part is solved. But I can't find anywhere about updating preloader based on the amount of data loaded, so any instructions would be helpful. There must be some obvious way,to calculate, or get info about data loaded in the background queue.
I don't do any progress bars since my levels take about a second to load. I have a seamless transition between levels. Before I was doing things this way my game would freeze for a moment in a transition because it had to load all the resources on the same thread that my game was running
I create a static method in my class to preload resources.
// config is a struct with many parameters
class func createResources(config: HyperSceneConfig, withCompletion: (scene: HyperScene) -> ()){
// load resources on other thread
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), {
let hyperScene = HyperScene(config: config)
// callback on main thread
dispatch_async(dispatch_get_main_queue(), {
// Call the completion handler back on the main queue.
withCompletion(scene: hyperScene)
});
})
}
my scenes init
init(config: HyperSceneConfig) {
super.init(size: config.size, viewController: config.viewController)
self.backgroundColor = SKColor.blackColor()
self.levelTime = 200
// this is where i do all my setup before the scene is presented
self.setupScene()
}
this is how I present my scene in my gameViewController.
You could do the same sort of thing in a scene to load the next level. This is great because you can create a seamless transition between levels since everything is loading on a different thread.
HyperScene.createResources(hyperConfig, withCompletion: {
scene in
self.scene = scene
self.scene.scaleMode = .AspectFill
self.skView.presentScene(self.scene)
self.view.addSubview(self.skView)
})
I'm newbie in using ogre3D and I need help on a certain point!
I'm trying a library mixing ogre3D engine and qtml :
http://advancingusability.wordpress.com/2013/08/14/qmlogre-is-now-a-library/
this library works fine when you want to draw some object and rotate or translate these objects already initialise in a first step.
void initialize(){
// we only want to initialize once
disconnect(this, &ExampleApp::beforeRendering, this, &ExampleApp::initializeOgre);
// start up Ogre
m_ogreEngine = new OgreEngine(this);
m_root = m_ogreEngine->startEngine();
m_ogreEngine->setupResources();
m_ogreEngine->activateOgreContext();
//draw a small cube
new DebugDrawer(m_sceneManager, 0.5f);
DrawCube(100,100,100);
DebugDrawer::getSingleton().build();
m_ogreEngine->doneOgreContext();
emit(ogreInitialized());
}
but If you want to draw or change the scene after this initialisation step it is problematic!
In fact in Ogre3D only (without the qtogre library), you have to use a frameListener
which will connect the rendering thread and allow a repaint of your scene.
But here, we have two ContextOpengl: one for qt and the other one for Ogre.
So If you try to put the common part of code :
createScene();
createFrameListener();
// La Boucle de rendu
m_root->startRendering();
//createScene();
while(true)
{
Ogre::WindowEventUtilities::messagePump();
if(pRenderWindow->isClosed())
std::cout<<"pRenderWindow close"<<std::endl;
if(!m_root->renderOneFrame())
std::cout<<"root renderOneFrame"<<std::endl;
}
the app will freeze! I know that startRendering is a render loop itself, so the loop below never gets executed.
But I don't know where to put those line or how to correct this part!
I've also try to add a background buffer and to swap them :
void OgreEngine::updateOgreContext()
{
glPopAttrib();
glPopClientAttrib();
m_qtContext->functions()->glUseProgram(0);
m_qtContext->doneCurrent();
delete m_qtContext;
m_BackgroundContext= QOpenGLContext::currentContext();
// create a new shared OpenGL context to be used exclusively by Ogre
m_BackgroundContext = new QOpenGLContext();
m_BackgroundContext->setFormat(m_quickWindow->requestedFormat());
m_BackgroundContext->setShareContext(m_qtContext);
m_BackgroundContext->create();
m_BackgroundContext->swapBuffers(m_quickWindow);
//m_ogreContext->makeCurrent(m_quickWindow);
}
but i've also the same error:
OGRE EXCEPTION(7:InternalErrorException): Cannot create GL vertex buffer in GLHardwareVertexBuffer::GLHardwareVertexBuffer at Bureau/bibliotheques/ogre_src_v1-8-1/RenderSystems/GL/src/OgreGLHardwareVertexBuffer.cpp (line 46)
I'm very stuck!
I don't know what to do?
Thanks!
Hey guys, I'm trying to make a 2D Platform style game similar to this game below:
http://www.gameshed.com/Puzzle-Games/Blockdude/play.html
I have finished making most of the graphic, and areas, and collision, but our character is still not able to carry things. I'm confused as to what code to use so that my character can carry the blocks. I need help as to how to make our character carry blocks that are in front of him, provided that the blocks that don't have anything on top of it. This has been confusing me for a week now, and any help would be highly appreciated. :D
I fondly remember my first AS2 game. The best approach is probably an object oriented approach, as I will explain.
In AS2, there is a hittest method automatically built into objects. There is a good tutorial on Kirupa here:
http://www.kirupa.com/developer/actionscript/hittest.htm
also
http://help.adobe.com/en_US/AS2LCR/Flash_10.0/help.html?content=00001314.html
First you'll want to generate your boxes using a Box class. Your class would need to look something like the following:
//Box.as pseudo-code
class Box {
var x_pos:Number;
var y_pos:Number;
var attachedToPlayer:Boolean;
function Box(_x:Number, _y:Number) {
this.x_pos = _x;
this.y_pos = _y;
}
//other code here
}
See this tutorial on how to attach a class to an object in the library:
http://www.articlesbase.com/videos/5min/86620312
To create a new Box, you'd then use something like
box1 = new Box(100,200);
// creates a box at position 100x,200y
However, you'll also want to store the blocks you want to pickup into some sort of array so you can loop through them. See http://www.tech-recipes.com/rx/1383/flash-actionscript-create-an-array-of-objects-from-a-unique-class/
Example:
//somewhere near the top of your main method, or whereever your main game loop is running from - note Box.as would need to be in the same folder
import Box;
//...then, somewhere before your game loop
//create an array to hold the objects
var boxArray:Array = new Array();
//create loop with i as the counter
for (var i=0; i<4; i++)
{
var _x:Number = 100 + i;
var _y:Number = 100 + i;
//create Box object
var box:Box = new Box();
//assign text to the first variable.
//push the object into the array
boxArray.push(box);
}
Similarly, you would need a class for your player, and to create a new Player object at the start of your game, e.g.
var player = new Player(0,0);
You could then run a hittest method for your player against the blocks in your array for the main game loop (i.e. the loop that updates your player's position and other game properties). There are probably more efficient ways of doing this, e.g. only looping for the blocks that are currently on the screen.
Once your array has been created, use a foreach loop to run a hittest against your player in your game's main loop, e.g.
//assuming you have an array called 'boxArray' and player object called 'player'
for(var box in boxArray){
if (player.hittest(box)) {
player.attachObjectMethod(box);
}
}
This is basically pseudo-code for "for every box that we have entered into the array, check if the player is touching the box. If the box is touching, use the box as the argument for a method in the player class (which I have arbitrarily called attachObjectMethod)".
In attachObjectMethod, you could then define some sort of behavior for attaching the box to the player. For example, you could create a get and set method(s) for the x and y position of your boxes inside the box class, along with a boolean called something useful like attachedToPlayer. When attachObjectMethod was called, it would set the box's boolean, e.g. in the Player class
//include Box.as at the top of the file
import Box;
//other methods, e.g. constructor
//somewhere is the Player.as class/file
public function attachObjectMethod (box:Box) {
box.setattachedToPlayer(true);
//you could also update fields on the player, but for now this is all we need
}
Now the attachedToPlayer boolean of the box the player has collided with would be true. Back in our game loop, we would then modify our loop to update the position of the boxes:
//assuming you have an array called 'boxArray' and player object called 'player'
for(var box in boxArray){
if (player.hittest(box)) {
player.attachObjectMethod(box);
}
box.updatePosition(player.get_Xpos, player.get_Ypos);
}
In our Box class, we now need to define 'updatePosition':
//Box.as pseudo-code
class Box {
var x_pos:Number;
var y_pos:Number;
var attachedToPlayer:Boolean;
function Box(box_x:Number, box_y:Number) {
this.x_pos = box_x;
this.y_pos = box_y;
}
public function updatePosition(_x:Number, _y:Number) {
if (this.attachedToPlayer) {
this.x_pos = _x;
this.y_pos = _y;
}
}
//other code here
}
As you can see we can pass the player's position, and update the box's position if the attachedToPlayer boolean has been set. Finally, we add a move method to the box:
public function move() {
if (this.attachedToPlayer) {
this._x = x_pos;
this._y = y_pos;
}
}
Examples of updating position:
http://www.swinburne.edu.au/design/tutorials/P-flash/T-How-to-smoothly-slide-objects-around-in-Flash/ID-17/
Finally, to make it all work we need to call the move method in the game loop:
//assuming you have an array called 'boxArray' and player object called 'player'
for(var box in boxArray){
if (player.hittest(box)) {
player.attachObjectMethod(box);
}
box.updatePosition(player.get_Xpos, player.get_Ypos);
box.move();
}
You have also specified that the blocks should only move with the player if they have nothing on top of them. When you call your attachedToPlayer method, you would also need to run a foreach loop inside the method between the box and the objects that might sit on top of the box. You should now have a fair idea from the above code how to do this.
I appreciate that this is quite a lengthy answer, and I haven't had an opportunity to test all the code (in fact I'm fairly positive I made a mistake somewhere) - don't hesitate to ask questions. My other advice is to understand the concepts thoroughly, and then write your own code one bit at a time.
Good luck!
The way I would do this is to design an individual hit test for each block he will be picking up, then code for the hit test to play a frame within the sprite's timeline of him carrying a block, and to play a frame within the block to be picked up's timeline of the block no longer at rest (disappeared?).
Good Luck if you're confused about what I've said just ask a little more about it and I'll try to help you if I can.
