360 problem

[MechatheSlag]

I got this object which circles around another object.

This may sound strange, but I want the circle (it uses Alterable Value A to set it's angle) to go the closest direction of the pressed button.

IE: Pressing up and the object is to the left, it takes the right turn to the top and not the left turn.


Please help :3

Suppose that X is the angle you want to rotate to, and A is the current angle of the object. You need four events:

*A<X
+X-A<=180
 -->Add 1 to A

*A<X
+X-A>180
 -->Sub 1 to A

*A>X
+A-X<=180
 -->Sub 1 to A

*A>X
+A-X>180
 -->Add 1 to A

You also need to make sure X and A will "loop around" if they are greater than 359 or lower than 0. If you use an object's "angle" attribute then this will happen automatically (I think).

I'm afraid that doesn't work at all D=

Example: X = 270, A = 0.
A < X
X - A >= 180
Add 1 to A.

See how that just messes up and turns the wrong way?

Bump as this really matters to me D=

You can use the advanced direction object. That lets you rotate to a certain over time.

Could you make an example? I don't have much experimence with the Advance Direction Object <img src="/center/images/graemlins/frown.gif" alt="" />

Not really. I don't have mmf2 on this computer and the computer I do have it on is rendering a large 3d scene.

It's an expression in the advanced direction object called rotate towards angle or something like that. It should be pretty self explanatory.

A &lt; X
X - A &gt;= 180
Add 1 to A.

Erm, I never typed that event. Check the events I wrote up there again, in this situation A would be decremented. I have used these events and they work just fine. There is no need for an extension in this situation, although if you want to take the slightly easier route I guess that's OK.

It was an example of 2 values which would screw up what you made. If it works for you, though, you could post an example as I pretty much need this D=

...anyone?
