can someone help me?
pico8 is complaining it can't find the obj table on line 132.
it also is printing out weird traces

Hum...
init calls add, add calls init...boom!

P#55259 2018-08-16 16:21 ( Edited 2018-08-16 20:21)

it should only be calling the parent's init

so like add calls plr's init which calls add on thr which calls obj init
is there a better way to do this?

P#55266 2018-08-16 17:28 ( Edited 2018-08-16 21:28)

Option 1: fix the code (change init/add to avoid inifinite loops)
Option 2: start off clean and really understand pieces of code you probably gathered from some other post
Option 3: keep it simple. Do you really need nested init and such?
