Tried importing the GMS2 version in GMS2.2.0.343 and it had one error, there's a mistake in player_score (Scripts-->Gameplay-->Player-->Score Lives Etc) where it uses the calling instance's x/y instead of argument0/argument1. The body of the script should look like this, then it compiled fine for me:
if(argument3 && argument2 > 8000){
global.playerlives++
effect_spawn_textpopup(argument0,argument1,"1UP",c_lime,c_teal,font_retro)
}
else{
global.playerscore += argument2
effect_spawn_textpopup(argument0,argument1,string(argument2),c_white,c_black,font_narrow)
}(Alternatively you could use argument[2] instead of argument2 and so on for the other arguments, this might be why you get an array index error)If this doesn't solve the problem for you, could you please copypaste the entire error message? Usually it hints at where the error occurs.
