Following a tutorial: Custom entity Won't Spawn (new to the api)

I think it's something to with staticdata to somehow naming the entity? I literally just followed a tutorial.

I've been focusing on this for hours (I will back to this forum in 15 minutes)... If someone could help with this it would be greatly appreciated...

I think the problem is that you call minetest.add_entity inside on_activate. Since minetest.add_entity calls on_activate again, the code never finishes running.

There seem to be other issues with the code, but you can probably fix them once you fix this first bug.

AsyncErr: Lua: Runtime error from mod 'intelli_ai' in callback environment_Step(): ...er\minetest-5.6.0-win64\bin\..\builtin\common\vector.lua:212: attempt to index local 'a' (a nil value)
stack traceback:

I think this is good news because then it's a time consitency problem

I'm starting a an easier project once my code is ready to move on.... I love your slugs mod
