Ok so i took the robots from the fps tut, and made them targets of each other, problem is when one kills the other, he still tries to find the robot. Is there a way to edit the robot script so that, he continues to help my character?
make an array of all the robots in the level. use GameObject.FindGameObjectsWithTag
make an empty gameObject variable
then use a while loop or for loop to go through the array, save any of the robots that are not this robot into the gameObject variable
if gameObject variable contains a robot, keep looking, else, dont.
you can always keep track of what your robot is supposed to do in a variable. exp, if doingWhat == 1, look for other robot, if doingWhat == 2, look for player
then you create a bunch of if statements that the robot will ask and use to determine doingWhat.
this way, you can separate how the robot makes decisions and takes action.
im new to programming so i dont know how this should all be written out
here is the script, what, where, and how should everything be wrtten?
var speed = 3.0;
var rotationSpeed = 5.0;

Thank You!
it’s a little hard for me to tell whats what. think you could post just the part of the code that is giving you trouble?
that’s the problem, with this script i get no errors, just from the script.
It’s when a robot kills the robot that he is targeted for.
Ex:
Robot A
Robot B
Robot A is targeted on robot B
So robot a kills Robot B, then an error comes up saying the target is not present, or something to that effect. Becuase robot a is still trying to find robot b which is dead.
The robot doesn’t stop attacking when the other robot dies.
To solve this, simply check at every update if the targeted robot is dead, and exists.
To check if something exists:
if (target.gameObject) - returns false if object does not exist.
Or if something is dead:
if (target.GetComponent(roboscript).isdead) - returns the value of the variable “isdead”, from the targeted robot, assuming that roboscript is changed to the exact name of the robot’s script.
If target.gameObject returns false, or target.GetComponent(rboscript).isdead doesn’t, simply stop attacking.
To do this:
Put the attacking code inside the logic checks stated above.
haha i just like how you called it a roboscript.
