How do an actor rotate on center point? Thanks.

For example, a cannon rotate around center point with 360 degrees.

    Reviving this thread, if someone knows the answer please post.

    I want my moving hero to rotate once, 360 degrees around its centre point when space bar is pressed?

    When Space is pressed
    --Interpolate rotation to 360

    Still can't implement the control

    Try maybe to rotate to + or -359.999, maybe GS thinks 0 and 360 is the same so it's not moving it... Not sure

    Can you describe the steps you went through to create the rule - and any other additional rules for the actor that might be effecting it ?

    Interpolate is simply changing one value to another through all the intermediate steps, so it wouldn't really make any difference whether the target value was 360 or even 1440.

    This is how I would do it (demo attached):

    Is this the way I should do it?

    There is accelerate attributes on the actor as well, but does that affect it though?

    No. That will interpolate the rotation TO 360°. Not THROUGH 360°, which is what you want. See my demo above.

    Not sure what you're asking since you haven't explained what attributes and how you're accelerating the actor.

    Oops... I made a slight error in the file. Forgot to store the starting rotation... one sec and I'll upload a new version.

    Edit: Okay, my post above has the fixed file and updated screenshot.

    You can simply interpolate the rotation to 360 (or -360), you don't need the start rotation attribute.

    I've seen that, I was asking if you could share the steps you went through to create the rule and any other rules the actor might have.

    Looks to me like you created the 'rotation' attribute yourself ?

    It does work! But only if self.rotation starts at 0, right?

    Yes, it assumes a default starting angle of 0°, any other angle (or changing angles) and then I'd use your approach of a starting angle attribute.
