Yeah, that's what I needed. I didn't know what had to go in that json. It makes sense now I can see one. I tried TexturePacker ... hmmm, the free version is crippled, not limited, actually crippled. Even a two frame animation gets overwritten with "buy me" logos. I'll look into the other tools mentioned. Thanks folks
I'm trying to create a six frame movie. I'm at a loss for what the related sprite sheet json file should have in it. I keep seeing example code for loading the json file but not a hint for what needs to be in the file. Any good resources/examples about?
