I have a boat that the user controls on a matrix that dynamically randomizes (for the waves). How would I make the boat angle and pitch itself so that it is parallel to the matrix below it at all times?

i suggest making it simple. Have maybe four points on your boat (front left, front right, back left, back right) and have the program check the matrix height at those four points and write some sort of equasion to find the boats pitch, maybe through finding the slope of a tangent line between the points.

good luck!

I have no idea how they did it, but in the "jetski" example in DB regular, there was a jetski that bobbed in angular coordination with the waves. Used a few sin and cos commands though, I'm sorry to say. Good luck with that.

It wasn't in full 3D angular movement, actually. I seem to recall that the jetski tested a point in front of it and a point behind it; it then determined an appropriate angle to be at and interpolated it over time for smooth movement. In essence, the jetski never tilted sideways - just backwards and forwards.

Perhaps the tank demo would be more handy; although, it is a little complicated at first. If you can't get your head round what it does, come back here and we'll see if we can help.
