up/down rotation 'barricade' doesn work

Unity Engine
1

Hi i was wondering what am i doing wrong

i have a tanks’ gun and i can rotate it up/down but i want to restrict how mouch up or down you can rotate

float curRot = gun.rotation.z;
if(	gun.rotation.z == Mathf.Clamp(curRot,0,17) )  {
	//rotate
}

unfortunetly this doesn’t work … any suggestions?

transform.rotation isn’t represented in Euler angles, but Quaternions. For your examples you’d want to use gun.rotation.eulerAngles.z, but even THAT won’t work since you can’t modify single parameters of a Vector3. The correct approach would be to clamp curRot directly, then do gun.rotation.eulerAngles = new Vector3(gon.rotation.eulerAngles.x, gun.rotation.eurlerAngles.y, curRot).

i was goofing around with it and i got this monster :slight_smile: wasn’t sure how to use mathf.clamp effectyvly

if (rotateTouchPad.position.y > 0) {
			if(	(gun.rotation.eulerAngles.z < 17  gun.rotation.eulerAngles.z > 0) || (gun.rotation.eulerAngles.z < 360  gun.rotation.eulerAngles.z > 347) || gun.rotation.eulerAngles.z == 0 || gun.rotation.eulerAngles.z == 360 )
				gun.Rotate (up);
}

if (rotateTouchPad.position.y < 0) {
			if((gun.rotation.eulerAngles.z <= 17  gun.rotation.eulerAngles.z > 0) || (gun.rotation.eulerAngles.z <= 360  gun.rotation.eulerAngles.z > 347) || gun.rotation.eulerAngles.z == 0 || gun.rotation.eulerAngles.z == 360)
				gun.Rotate (down);	
}

the problem is when i go max up or max down i can’t go in diffrent direction … probably goes out of restricted area

up is vector 3 (0,0,1)
down is vector 3 (0,0,-1)

i tweaked it works :slight_smile: thanks for clearing that up for me

Mathf.clamp(a,b,c) essentially reads like this:

“If value a is between b and c, return it as is. If it goes outside of the b-c boundary, limit it to one of those.”
