In my game I have found a problem implementing the AI. I have some Lua scripts that request the entity instances from the host application and receive the instance as a pointer. I found that I need a way to signal the scrit that such entity no longer exists (for example, was killed). My question is, is it safe to return 0 as pointer value to tell the script that such entity no longer exists? -- Roger D.
