The lasers in my project aren't showing up when I run everything. They appear (animated) in the scene tester for Level Helper and I've saved everything and I believe the Animations.pshs file is in the correct spot. Any suggestions? Thanks a ton!

Make sure your animation image files and pshs files are in the resource folder. Cocos2d should print an error message in the console if it does not find the image files but you need to be in debug mode.

Hi I am experiencing a similar issue. I have made sure that all the animation files are included in the project, but I get an error saying "No active frame in animation laserAnim..."

Any idea how to fix the issue?

Hey,

Does it crash? This is a log message that i put in case something is wrong but i never seen this log before actually printing. So can you post some code or send me the project to see whats going on? vladu dot bogdan @ gmail dot com

no, it doesn't crash, just runs very slow at about 20 fps.

I'll send you the project.

Thanks for the help.

The problem with your project was as follows

1. "Animations" spritehelper document - had previously sheet named "Animation" then you saved then you changed the sheet name to "animation" (lower A) but images where not saved anymore. this caused xcode to not find the texture file. Just remove the image files and resave this scene.


2. And the most inportant problem, in the other spritehelper document that you have, you had an empty animation called "laserAnim" this was empty - no frame in it.

You also had "laserAnim" in the "Animations" spritehelper document. Inside LH you assigned the "laserAnim" that was empty to the sprite.

This caused this problem.

Just remove "laserAnim" animation that is empty from the backgrounds SH document and assign the good "laserAnim" to the sprite then resave.

AWESOME! That's for the help.

Do you have any idea why it's running at 30 fps?

Test on the real device for accurate fps. Optimize physical shapes for better performance. Set "Allow Sleep" in SH also improves performance (enabled by default)
