Constraining help

mc99093

I'm creating a bulldozer and I'm having trouble with the pushing arm. I want it to be able to rotate up and down freely and move with the bulldozer. I've constrained the arm X and Y positions to a offset point for the rotation which works great. I don't know how to keep it constrained to the body of the bulldozer to move with it since the X and Y positions are already constrained for the offset rotation. I've included the project any help would be great.

You just need to add the bulldozer's position to the constrain behaviours.

I've attached a (simplified) example file.

No problem, obviously the attribute called 'Rotation Angle' in the arm actor controls the angle of the arm, so you can control this however you like for your game, for instance via a dial or slider or - as it is now - a simple click that interpolates the angle between two values.
