selectedtarget = distancetoTarget; is wrong

distancetoclosesttarget = distancetotarget

[finite radish]

Fixed, now have "unassigned local variable 'ClosestTarget'"

[noble trail]

change

GameObject closestTarget;

to

GameObject closestTarget = null;

[finite radish]

That fixed it

yay

[finite radish]

Thanks! Now going to the older messages about preventing the nullreference exception

[noble trail]

but

you need to protect select target at bottom from being null

if the foreach loop doesn't select anything you're setting select target to null

keep that in mind

Got you

I'm going to attempt to bang my head on the API a bit more for that one before asking for more help here

[finite radish]

Yeah, tried a couple different null reference exception fixes but none of them worked, and it's 10 AM

Can null reference exceptions crash a game?

Or can I successfully slap a patch on somewhere to just clear the error cache every once in a while?

NVM, fixed

Thank you guys for all your help! This is easily some of the more confusing programming Ive had to do

Oh boy, new problem
