For un unknown reason, DontGoThroughThings fails when deploying my app to iOS...

@attiksystem I've used it in iOS and I tend to doubt it's an issue with the script. Can you give more details?

Hi, sure. When attaching DontGoThroughThings to my object (Cloth Renderer, I'm not sure this has an effect), and deploying to iOS, it bombs at line 0x81a0, with error "Thread 1: EXC_BAD_ACCESS (code=1, address = 0x0)". Using Pro version of the tools, latest version of everything.

@attiksystem no render should present any effect on this. the "line" the assembly code doesn't help as I'm not fluent in it. also EXC_BAD_ACCESS tells me nothing without knowing what was in the original (rather than assembly) line that triggered it - since I don't have a "knowledge base" of the script possible errors... I advice you to create an empty scene, free of errors, and little by little build and test something that can emulate what you need. Then attach the script. If, by any chance, you find any errors there, you'll have a much better idea what could have caused it.

Thanks. I'll try that. But meanwhile, I found another trick in order to avoid objects to "go through" other objects: make one of them very thick. This might not work all the time, but for my particular application, it does!
