I am working on a Dragon Warrior - type rpg game in Game Maker studio and can't figure out how to get a show choice option that doesn't use the mouse. I have setup the game to run completely with a gamepad, but when I am confronted with the situation that requires feedback (choice selection) from the player I am unable to get the gamepad working. Heres the GML
if (distance_to_object(obj_judy)) <= 64 {
if keyboard_check(vk_space) || gamepad_button_check_pressed(0, gp_face3) {
show_question(mine_crystal);
if true {
global.energy -= 10;
global.power_crystal += 1;
instance_destroy();
}
}
}
The problem is " show_question(); " uses a windows-type popup and doesn't work with the gamepad.
How do I get feedback from the player using only inputs from the gamepad?
Thanks for your time reading and your help with this small issue.
So yeah, you'll need to write that logic yourself. Also, that code you wrote there looks kinda scary, i'd use this;
if (show_question(mine_crystal) == true) {
global.energy -= 10;
global.power_crystal += 1;
instance_destroy();
}
because
show_question(mine_crystal);
if true {
global.energy -= 10;
global.power_crystal += 1;
instance_destroy();
}
Will show a question, and then always do the mine crystal action (because your if (true) will always evaluate to true, it doesn't know about the line above

I have been working with VCL for a couple months now, and could solve all my problems by googling, but this one got me stuck.
I want to color a row in a TListView whenever the subItem at index 7 of that row does not contain a certain text (see code below). It all works well, except that the caption-cell (furthest to the left) of the last row does not get colored. I tried a couple hacks (e.g. enabling and then disbaling the ListView when drawing an item), but I didn't find one that doesn't break other stuff on the form (e.g. timers).
Also, after I click on the cell, it does get colored...
I'm using XE7 (C++Builder) on Windows 7.
All suggestions are appreciated ;)
void __fastcall TBackupManagerForm::OverviewListViewCustomDrawItem(TCustomListView *Sender, TListItem *Item, TRect &Rect, TOwnerDrawState State)
{
if ((*Item->SubItems)[7] != "someText") {
Sender->Canvas->Brush->Color = clRed;
}
else {
Sender->Canvas->Brush->Color = clWindow;
}
TRect r, rt;
r = Item->DisplayRect(drBounds);
Sender->Canvas->FillRect(Rect);
r.Right = r.Left + (*OverviewListView->Columns)[0]->Width;
rt = r;
rt.Left += 5;
rt.Top += 1;
UnicodeString s = Item->Caption;
Sender->Canvas->TextRect(rt, s, TTextFormat()<<tfSingleLine<<tfEndEllipsis);
for (int i = 0; i < Item->SubItems->Count; i++) {
ListView_GetSubItemRect(Sender->Handle, Item->Index, i+1, LVIR_BOUNDS,&rt);
s = (*Item->SubItems)[i];
Sender->Canvas->TextRect(rt, s, TTextFormat()<<tfSingleLine<<tfEndEllipsis);
}
}
EDIT
(Answering comments here because not enough rep :P)
#PaulMcCarthy Yeah, that seemed weird to me too...
#RemyLebeau Thanks for the suggestions, I implemented them.
Also, I managed to get it drawn properly by making an extra call to OverviewListView->Refresh() from outside CustomDrwaItem, but it still bugs me that it didn't work without it (pun somewhat intended).
I am having some trouble with programming hit detection in Processing.JS. I have tried to make a function that checks if something is touching an object and returns true and otherwise returns false. This is that here.
`Box.prototype.checkTouching = function(v){
if(v.position.x > this.position.x - this.width/2 && v.position <
this.position.x + this.width/2 && v.position.y > this.positon.y -
this.height/2 && v.position.y < this.position.y + this.height/2){
return true;
}else{
return false;
}
};`
I am implementing it by creating a new variable "b" in my draw function that holds the value the function returned then using an if statement to check if the value "b" is holding is true. Like so
var b = box3.checkTouching(mos);
if(b === true){
println("It works");
}
What should happen when the two objects touch is that a message saying "it works" gets printed in to the console. Unfortunately even when the object the function is running on is touching the object that is running it nothing happens. I have already checked to see if the logic works and it is valid so I know it has to be my implementation I just can not seem to find out what is wrong with my implementation. Can anyone tell what I am doing wrong? Full program here
You need to check whether the rectangles overlap. You'd do this by checking each side, like this:
if(rectOneRight > rectTwoLeft && rectOneLeft < rectTwoRight && rectOneBottom > rectTwoTop && rectOneTop < rectTwoBottom){
//collision
}
Shameless self-promotion: I've written a tutorial on collision detection in Processing (including rectangle-rectangle collision) available here.
To build on what Kevin posted, say I want to hover my mouse over a rectangle. processing has the built in variables mouseX, mouseY that return the coordinates of the mouse.
so I would check if the mouse X position was greater then the rect X pos, and less than the rect X pos + the rect width. the, do the same with the mouseY, rect Y and rect height
if (mouseX > rectXpos &&
mouseX < rectXpos + rectWidth &&
mouseY > rectYpos &&
mouseY < rectYpos + rectHeight) {
// the button is being hovered over
}
So i got this problem when one - two+ players are online the countdown timer goes in minus like this 4,3,2,1,0 -1,-2,-3 etc.
Does anyone know how i can fix this, been struggling with it for quite a long time now :P
Here is my countdown class:
#Override
public void run() {
if (timeUntilStart == 0) {
if (!Game.canStart()) {
if(Bukkit.getOnlinePlayers().size() <= 2) {
plugin.restartCountdown();
ChatUtilities.broadcast(ChatColor.RED + "Not enough players to start. Countdown will");
ChatUtilities.broadcast(ChatColor.RED + "restart.");
for (Player p : Bukkit.getOnlinePlayers()) p.playSound(p.getLocation(), Sound.ENDERDRAGON_WINGS, 5, 1);
return;
}else{
if(Game.canStart()) {
if(Bukkit.getOnlinePlayers().size() >= 2) {
Game.start();
}
}
}
}
}
boolean broadcast = false;
for (Player p : Bukkit.getOnlinePlayers()) {
p.setLevel(timeUntilStart);
if (timeUntilStart < 11 || timeUntilStart == 120 ||timeUntilStart == 60 || timeUntilStart == 30) {
p.playSound(p.getLocation(), Sound.ORB_PICKUP, 5, 0);
if (timeUntilStart == 1) p.playSound(p.getLocation(), Sound.ORB_PICKUP, 5, 1);
broadcast = true;
}
}
if (broadcast) ChatUtilities.broadcast(String.valueOf(timeUntilStart) + " ยง6Seconds until the game starts!");{
}
{
timeUntilStart -= 1;
}
}
}
The only case in which your method returns and timeUtilStart is not decremented is
timeUntilStart == 0 && !Game.canStart() && Bukkit.getOnlinePlayers().size() <= 2
As defined by the first three if blocks in your code.
This explains why your countdown does not stop when you have 3 or more players around.
I believe this mistake happened because of messy {} blocks and indentation. Take a step back and closely read the code you wrote again and fix brackets as well as indentation.
Good formatting is not a pointless chore, it's an essential tool to help yourself understand what you already wrote.
Have you tried using the bukkit scheduler? People tend to forget that bukkit's API can handle countdowns very well. Just call the scheduler with this
myInteger = Bukkit's.getScheduler.scheduleSyncRepeatingTask(plugin, new runnable(), 0L, 20L)
Put your JavaPlugin extension class in as plugin, use runnable adding unimplemented methods, 0L is ticks before first run, 20L is ticks between each run.
Cancel the countdown like this
Bukkit's.getScheduler.cancelTask(myInteger)
I am totally new at this whole programming thing, and I really need help. So basically, I'm trying to make a healthbar that will increase or decrease depending on what button is clicked. I made a healthbar movieclip with 101 frames (I included zero) and put this in the actionscript layer of the movieclip:
var health:Number = 0;
if(health == 0)
{
gotoAndStop("1")
}
if(health == 1)
{
gotoAndStop("2")
}
if(health == 2)
{
gotoAndStop("3")
}
and on and on like so. Basically, on the stage itself, I have a button called fortyfiveup_btn that is commanded to do this:
var health:Number = 0;
fortyfiveup_btn.addEventListener(MouseEvent.CLICK, fortyfiveupClick);
function fortyfiveupClick(event:MouseEvent):void{
health = health+45
}
I quickly realized that both health variables, the one for the button and the one for the healthbar will not interact. How can I make it so if the button is clicked, the health goes to the relevant frame or percentage?
Thanks for any answers, and I appreciate all the help I can get :)
If the answer == yes to my comment you should do this:
You need to give the movieclip an instancename (perhaps lifebar) and from stage you can access the health inside the "lifebar" with lifebar.health.
So you need this inside your stage:
//You can delete the var health:Number = 0;
fortyfiveup_btn.addEventListener(MouseEvent.CLICK, fortyfiveupClick);
function fortyfiveupClick(event:MouseEvent):void{
//You can write this, too: lifebar.health += 45;
lifebar.health = lifebar.health+45;
}
You can even optimize your lifebar script, don't use 101 times the if(health == x) you can use this, too:
gotoAndStop(health + 1);
(I think this is inside an ENTER_FRAME event?)
EDIT:
Some error countermeasures:
//Don't let health decrease below 0
if(health < 0) health = 0;
//And don't above 100
else if(health > 100) health = 100;
gotoAndStop(health + 1);
Use int instead of Number when you don't use decimal numbers and uint when you don't use negative integers (this bugs when the number can drop under 0, so for your health we take int):
health:int = 0;
I have been developing a very simple text game using Objective C and Xcode. It is almost done but I am having a problem, the scanf method stops the loop and asks for user input while I need the computer to be running the rest of the loop, the solution I came up with was running two while loops at the same time, one being the logic loop and another being a loop for user input.
I have been doing my research and it looks like using threads are the way to go, I just have not found a tutorial that will break it down for a n00b in Objective C (I am decent in java, I just have never worked with threads). If anybody could explain them or link me to a very broken down tutorial that would be great. Or if anybody has another idea I am open to anything else.
Necessary Code (The scanf I am having a problem with has asterisks on the line):
while(running != 0)
{
if(gameState == 1)
{
if(timeToGenerateNum == true)
{
while(randNumber < 10000000)
{
randNumber = arc4random() % 100000000;
}
NSLog(#"%i", randNumber);
timeToGenerateNum = false;
}
else
{
while(time <= 2500)
{
NSLog(#"Testing");
time++;
******************scanf("%i", &userNum);************************
if(userNum == randNumber)
{
score += time;
time = 0;
timeToGenerateNum = true;
}
}
NSLog(#"Game Over! Your score was %i!", score);
running = 0;
}
}
else if(gameState == 2)
{
NSLog(#"To play, simply type in the number that appears on the screen.");
NSLog(#"But be careful, you only have a short amount of time before GAME OVER!");
NSLog(#"The quicker you type in the number the more score you get!");
NSLog(#"Are you ready to start, if so type '1' and press enter!");
scanf("%i", &gameState);
}
}
You're going to have to learn a bit about BSD (Unix, Linux) input/output to pull this off: replace your call to scanf with a non-blocking function you write to acquire input from the user's keyboard.
This function should immediately return whatever the user typed, or immediately return with a zero character count if she didn't type anything.
Read up on the select(2) system call, and keep in mind that keyboard input (standard input) is the first file descriptor, file descriptor zero.
