I have a maths question - say for example there are two entities A and B travelling at constant speeds. The bearing of entity A is known and the x,y positions of both also. How would I calcuate the bearing of entity B which would cause the entities to intersect?

Are the speeds of entities A and B known? By constant do you mean they are traveling at the same speed?

By constant i mean the speeds dont change but the speeds of the two entities arnt neccesarily the same. I think this can be worked out by converting the two speeds into the sides of a triangle or using vectors but i havnt been able to work out or find a forumla.

The reason i ask this is for turret control in a game. The turret should fire a projectile at some point in front of a target based on the projectiles speed, the speed of the target and its bearing and their relative positions.

Ok, I get it. This sounds like something you could accomplish w/ vectors. Unfortunately, I'm new to DarkBASIC, and so I don't know much about vectors. Anyone else?

One by one, the penguins take my sanity away.
