apply an animated sprite on a mesh
« on: May 26, 2013, 02:40:11 pm »
is it possible with 2dtoolkit ?

i mean, first create a spritesheet, then an animation with 2dtk and apply this animated sprite on a mesh in unity ?

thus using complexe meshes and apply animated texture on them.

here's the mesh :


i'd like to apply animated texture on each part of this wheel.

You can't apply an animated sprite onto a mesh. If you wish to do this, just using material offsets will be easier to deal with.
Animated sprites are realised using meshes, and applying to a custom mesh with all the optimizations that tk2d performs, will be very expensive indeed. It will be much much easier to simply use a normal texture with UV scale and offset.

i managed to iterate through a spritesheet but the hard task is to start from anywhere and stop anywhere in a spritesheet with loop options...

Don't you just want to grab the animation clip and get the frames from there if you want to?
Again, the issue is gonna be applying the uvs to a model, it can be rotated, clipped, etc.

i'm not sure to understand but as you suggested, i've done the script myself, not trying to use a tk2d animation sprite anymore.

so i made a 2k x 2k spritesheet myself, applied it on a mesh and that works but when it comes to looping on certain frames, that's where i get stuck...

If you're doing your own spritesheet, you can probably steal the logic from tk2d Sprite. I don't know what you've done, so I couldn't really help you with that. But you do have something that works - the tk2dAnimatedSprite, just use that as a basis for your stuff.
