How to set a maximum turret rotation with touch?

Hello,

I'm trying to make something where the user uses touch to direct fire.

As you can see, I have no idea what I am doing.

This works in a way, but the left and right side their angles differ from where I set the turret sprite (horizontal X position).

I suspect it has something to do with the Touch coordinates messing with the numbers of the max angle.. but I'm not sure.

I just want the turret to go max 200 degrees (which is the max angle left) and 340 degrees (max angle right).

The turret starts with an angle of 270 (pointing up).

Any ideas?

Regards

Try this:

Turret set angle to clamp(angle(Turret.x, Turret.y, Touch.x, Touch.y), -160, -20)

Thanks!! That works like a charm.

You are a very helpful member.

I was wondering though, how did you get to the values -160 and -20?

Thanks again.

-160 is the same as 200 degrees.

angle() expression returns negative values for angles between 180 and 360.

OK thanks. Why does it return negative values between only 180 and 360 though? That makes it confusing to me :P

Thanks for the explanation. I still need to process it, but now I know how it works.
