Turret.cs(11,18) Cannot implicitly convert type ‘UnityEngine.GameObject’ to ‘UnityEngine.Transform’
I do not understand what is wrong or how to fix this and google isnt turning up any results
theres no actual weapon for the turret yet. I am just trying to do this in smaller bite sized steps as I am not proficient in c#. This current script is trying to search for the closest player/NPC, and then it will rotate the weapon (a dish thats supposed to represent a parabolic mirror) to aim at its target

So you’re saying you don’t know the difference between a Transform component type and a GameObject type? They’re completely different things i.e. types. Square peg, round hole. :slight_smile:

It tells you Line 11, Column 18. You only then have to look at what “target” is and see you’ve defined it as a Transform. You then look at your “FindClosestEnemy()” method and see it doesn’t return a Transform but a GameObject.

my brain didnt catch this and I realized what was wrong
fixed it by changing target = FindClosestEnemy(); to target = FindClosestEnemy().transform; and it worked perfectly
