(solved) Angle between two objects

by jeremy young · in iTorque 2D · 05/28/2011 (7:42 am) · 3 replies

I'm fairly new to torque and I love it. I need to find the angle between two objects and was wondering if there is an easy way to figure it out or should I just figure the diference between the x and y coordinates and do some right triangle trig math. Any help would be awesome. I have been reading, coding, and reading code but I can't seem to find out.

    You have to remember that angles are defined between vectors, not positions. So you have to decide if your are looking for the angle between the vectors that are formed from the objects positions and the origin of the coordinate system or are you looking for the angle between the objects directional vectors?

    Either way you have to use trig to figure this out.

    Thanks for the quick response, I was able to get it working from the direction you pointed me in. this is what I ended up with.

    [code]%vector = t2dVectorSub(%playerposition, %mousePosition);
    %angle = mRadToDeg(mAtan(%vector.y, %vector.x)) + 90;

    %sidea = getWord(%vector, 1);
    %sideb = getWord(%vector, 0);


    %power = mSqrt((%sidea * %sidea) + (%sideb * %sideb));
    %power *=15;

    player.setImpulseForcePolar(%angle, %power, false);[code]

    Glad you got it working. :)
