I'm using Blender 2.8 and I just have 2 objects: hand and gun and I want to create animations for them. So, for instance, I want to create a simple firing animation. What I do:
1. I create animation for gun
2. I create animation for hand
But if I switch somehow incorrectly I "lose" the first animation I've created. I tried creating fake users and stuff. I just don't get why I select the armature for which I've just created the animation, it plays, but there are no keyframes.
Here's the vid, here's the file.
Ask me questions if you have any.
The movement may be cached in Blender, you may need to reset the movement cache.
Alternatively, you should look at both the Track Controller and Dopesheet(action editor) - the animation may be stored in both.
The movement could be related to parenting ( to an object that is moving )
The movement could also be caused by physics simulation of a rigid body.
Hopefully with the help of the above, you find the problem.
I had the same problem. In the Animation mode (horizontal tabs across the top of the window), click on the object to animate.
The keyframes will appear.
If the object is not selected, the keyframes disappear.
Just leaving this here so that nobody spends 30 minutes trying to work this out, like i just did.

I've set up a SpringArm3d with a meshinstance as its child. The spring is set to 30m. Now, I want to rotate the child around the SpringArm3d by mouse motion. The easiest way to achieve this would be to rotate the parent, right? So I tried:
if event is InputEventMouseMotion:
$SpringArm3d.rotate_y(-event.relative.x * mouse_sensitivity)
While this does rotate the SpringArm, the child gets moved to the SpringArms position and is rotated there. I don't understand why the initial offset is not being kept? Do I need to use some other method for rotation?
I also tried the same setup, but with a Spatial3d instead of the SpringArm3d, and the child meshinstance just moved away in the viewport to create an offset. Same thing.
Any suggestions would be very welcome!
[I've asked the same question over at the Godot forums as well: https://godotforums.org/d/31388-rotating-child-around-parent-moves-child-to-parent]
EDIT: It seems this was caused by having to scripts using the same rotate_y(-event.relative.x * mouse_sensitivity) method, so eliminating it in one script seems to have solved the issue. (although I don't really see why that would be a problem in the first place)
thanks again in advance for any time spent helping me.
Thankfully, I have been able to import TMX to libgdx game without much of a problem, however this is now the first time of using Object Layer, for which at this moment in time I only want to include Platforms as the object (ie. I have 1x Tile Layer showing my background image and 1x Object Layer above). Now I've seen that I can just draw lines and/or boxes, circles etc to create 'zones' which I can pull into my code (goodness only knows how atm but I'll figure that later/soon )
But I see in Tiled that the button - Insert Tile (T) - exists.
I'm trying to use it but when the tile im using as a platform is placed it goes exactly where the mouse is pressed and I can't move it other than delete it. I'd just like to copy-paste a whole row of them for now and Level1 can just be 50 tiles in a flat line just so I can get it all working. It seems weird to me that Tiled can't do this but Ive spent ages looking for a way and can't find it.
Am I missing something or is this just not possible? And if the latter, how does an experienced tiled user (who's making a 2d platformer) go about creating such a simple example above in the Tiled environment?
What a noob - I answered my own question. The option I needed was in the 'View' dropdown menu -> 'Snap To grid' LOL
So, I have this code. It's a small 3D scene with a ground, a red box, a custom loaded building and a rotating "sun". I'm delegating camera navigation to OrbitControls script, as it fits the most the way I want the camera to behave, however, there is a little weird problem: after I zoom in into a 3D object within this scene, rotate a little, then zoom out to "leave" the object, the zoom out process takes a billion scrolls. It's a weird behavior and I'm sorry if I'm not clear enough; once I'm in I have to scroll like forever, and every frame it seems to move "out of" the object very slowly, like the camera state is somehow screwed up.
I'm sorry if this very question has been already asked, I looked for this issue and tried stuff from other topics that seemed the same, but it didn't work.
#Edit
Wow, something even weirder. I tested zooming in this example, indefinitely, then the zoom in started to grow VERY slowly (just like in my code). Am I misunderstanding something? It looks as if the amount of zoom-in's somehow blocked rendering or something.
WestLangley tip actually solved my problem. Setting minDistance prevented the camera to zoom in infinitely, despite the actual rendering only showing a small step into the scene.
Now I could be wrong about this but after testing it all day, I have discovered...
When adding a widget and setting the z-index, the value "0" seems to be the magic depth.
If a widget's Z is at 0, it will be drawn on top of everything that's not at 0, Z wise.
It doesn't matter if a widget has a z-index of 99, -999, 10, -2 or what ever... It will not appear on top of a widget who's z-index is set to 0.
It gets more strange though...
Any index less than -2 or greater than 2 seems to create an "index out of range" error. Funny thing is...when I was working with a background and sprite widget, the background's Z was set to 999 and no errors. When I added another sprite widget, that's when the -2 to 2 z-index limitation appeared.
Yeah I know...sounds whacked!
My question is, am I right about "0" being the magic Z value?
If so, creating a simple 23D effect like making a sprite move being a big rock will take some unwanted code.
Since you can only set Z when adding,a widget, one must remove and immediately add back, with the new Z value...a widget.
You'll have to do this with the moving sprite and the overlapping object in question. Hell, I already have that code practically written but I want to find out from Kivy pros, is there a way to set z-index without removing and adding a widget.
If not, I'll have to settle for the painful way.
My version of Kivy is 1.9.0
What do you mean by z-order? Drawing order is determined entirely by order of widgets being added to the parent, and the index argument to add_widget is just a list index at which the widget will be inserted. The correct way to change drawing order amongs widgets is to remove and add them (actually you can mess with the canvases manually but this is the same thing just lower level, and not a better idea).
I found a working solution using basic logic based on the fact widgets have to be removed and added again in order to control depth/draw order.
I knew the Main Character widget had to be removed along with the object in question...so I created a Main Character Parent widget, which defines and control the Main Character, apart from its Graphic widget.
My test involves the Main Character walking in front of a large rock, then behind it...creating a 23D effect.
I simply used the "y-" theory along with widget attach and detach code to create the desired effect.
The only thing that caught me off guard was the fact my Graphic widget for my Actor was loading textures. That was a big no no because the fps died.
Simple fix, moved the texture loading to the Main Character Parent widget and the loading is done once for all-time.
PS, if anyone knows how to hide the scrollbars and wish to share that knowledge, it'll be much appreciated. I haven't looked for an API solution for it yet but I will soon.
Right now I'm just trying to make sure I can do the basic operations necessary for creating a commercial 23D game (handhelds).
I'm a graphic artist and web developer so coming up with lovely visuals won't be an issue. I'm more concerned with what'll be "under the hood" so to say. Hopefully enough, lol.
Background: I recently got two monitors and want a way to move the focused window to the other screen and vice versa. I've achieved this by using the Accessibility API. (Specifically, I get an AXUIElementRef that holds the AXUIElement associated with the focused window, then I set the NSAccessibilityPositionAttribute value to move the window.
I have this working almost exactly the way I want it to, except I want to animate the movement of windows. I thought that if I could get the NSWindow somehow, I could get its layer and use CoreAnimation to animate the window movement.
Unfortunately, I found out that this isn't possible. (Correct me I'm wrong though -- if there's a way to do it this way it'd be great!) So I'm asking you all for help. How should I go about animating the movement of the focused window, if I have access to the AXUIElementRef?
-R
--EDIT
I was able to get a crude animation going by creating a while loop and moving the position of the window by a small amount each time to make a successful animation. However, the results are pretty sub-par. As you can guess, it takes a lot of unnecessary processing power, and is still very choppy. There must be a better way.
The best possible way I can imagine would be to perform some hacky property comparison between the AXUIElement info values for the window and the info returned from the CGWindow api. Once you're able to ascertain what windows in the CGWindow API match AXUIElementRefs, you could grab bitmaps of the current window contents, overlay the screen with your own custom animation draw of the faux windows, then as you drop the overlay set the real AXUIElementRef's to the desired-end-animation positions.
Hacky, tho.
