UPDATE!

This bug:

1. Open project in C2 (it's a single-file project)

2. Open sprite "block"

3. Re-name animation "block7" to "sand"

4. Save project

5. Re-open the sprite and look at that animation

6. There is no visual image

Then

7. Save project

8. Open sprite "block" again

9. Re-name animation "sand" to "block7"

10. Debug without saving

11. Error!

6. There is no visual image

Also can't reproduce in Space Blaster... do you mean renaming an animation? Animation frames can't be renamed.

Yeah sorry that's what I meant.

I can't reproduce:

1. Open Space Blaster

2. Edit Player

3. Rename 'Default' animation to 'Foobar'

4. Preview

Seems to work fine. Including your exact repro steps is helpful.

Sorry.

1. Open my game in C2 (it's a single-file proj, so it may only happen to those)

2. Open my sprite

3. Go-to my "block7" animation and re-name it to "sand"

4. Debug

5. Error!

This happens after I re-name the animation frame, close the sprite-editor, then re-open the sprite-editor and click on the animation. It doesn't affect in-game, but it's just a sprite-editor bug.

Happens when I re-name an animation and debug the project without saving, Because the Temp dir files don't update unless you save.

Did you do anything like rename or delete to the files of your project before you opened your project in C2?

Sorry dcrew, it doesn't count if you delete or rename files manually in Windows Explorer while Construct 2 is using them! Of course that will break it. I don't expect anyone who is encountering the bug is doing that. I think it is something in the editor which causes it, not modifying files outside of C2.

You could be right, but I'd consider asking people if they did anything to there files first before that, you never know! People may decide to rename/delete files for reasons I don't quite understand, Sorry if I couldn't help <img src="smileys/smiley18.gif" border="0" align="middle" /> <img src="smileys/smiley18.gif" border="0" align="middle" /> I tried <img src="smileys/smiley9.gif" border="0" align="middle" /> But failed <img src="smileys/smiley11.gif" border="0" align="middle" />

OMG, I REPRODUCED IT!!

<img src="http://screensnapr.com/e/gwKmhy.png" border="0" />

I saved my project as a project (Not a single file) and then closed C2, Wen't into the project animations folder and into one of my sprite folders, then renamed the folder of one of the animation names. Then opened the project in C2 and got it!

Found something similar!

I deleted the Temp folder in "AppData\Local" whilst my project was open. And then debugged my project and got that.

I have a heavy feeling people have automated thing which deletes the Temp folder every so often.

Cross off this one move the images they imported to a new directory, Just tried and that isn't the problem.

Closer to reproducing it, let me try the others.

EDIT

This isn't it: rename the file of the image

EDIT

None of these:

rename the sprite

rename the animation

This has never happened to me, but I'm pretty sure that the problem is when people move the images they imported to a new directory OR they rename the file of the image OR they rename the sprite OR they rename the animation.

Either way, I've never had it happen to me.
