How do i limit the angle of an IKconstraint

I made the arm of the character aim for the target with ikconstraint but i dont know what to do to limit it i dont want it to be able to aim 360 degrees

you should be able to put a HingeConstraint from the base to the next instance. Then go into the HingeConstraint’s properties and enable “Limits Enabled”. If you cannot find it you may need to change the “Motor/Hinge Type” to servo. Then simply enter in your range of motion!

I’m pretty sure you can’t set a direct angle limit (idk though I’m no expert on these kinds of things). I do believe however there are some bypasses to this.

Limiting joint rotation: using BallSocketConstraint or Motor6D limits (like the shoulder’s UpperAngle).

Clamping the target’s position: in a script to stay within a certain angle or cone in front of the character.
You should also be able to combine both.
