I'm having a problem with Body.Rotation. I'm doing math with angles, and it's troublesome when Body.Rotation is not constrained between (-PI and PI).
Unfortunately, it cannot be set, and doesn't make any mention of what happens on MinRotation.
Why is not constrained in the first place?
To try to solve this, I use MathHelper.WrapAngle(Body.Rotation). For reason, it doesn't actually WrapAngle until it's already made like, 4 incorrect calculations.
To test the code I'm thinking of:
float Rotation2=(float)Math.Atan2(Mouse.Y - Body.Y, Mouse.X - Body.X);
//Rotation2 is the direction from Body to Mouse.
//weight can be any number, (0,1) noninclusive.
From here, you can draw a line from
(0,0) to (100,CalcRotation) //polar coordinates
Create a second body, whose Rotation is CalcRotation
Draw text of CalcRotation
Either way, you'll see that there is a lapse when the incorrect Body.Rotation is used when it jumps from -PI to PI.
Thanks for the help
