[SOLVED] Doing sprite animations for 2D game

[paul.whitham]

Hi 

 

What is the workflow for animations of sprites for a 2D game?

 

Do you have any examples and code?

 

Thanks

Paul

Paul, first time that anybody asked for 2D games with UNIGINE 3D engine (might be quite an overkill...).

 

Animation of sprites (as far as I understand it) is more a general asset modelling issue (e.g. texture atlas generation with backed animations presented via some simple 2D billboard) and not bound to a specifc engine. Also no UNIGINE sample available for 2D game use case, sorry.

Thanks Ulf for replay :)

 

Would it not be easy to change the texture thats used by the material and what would be the fastest way to do this in code?

 

Thanks

Paul

Easiest approach would be to provide a texture atlas divided into regular cells with all your animation frames as material texture. During runtime the texture animation can be easily done via time-animated material texture transform parameter offset/scale operations. See here
