Homing missile lead collision

[Flanker]

Hello, a few years ago I posted an explanation about lead collision on the BB forum : http://mojolabs.nz/posts.php?topic=105060

I revisited it with an even simpler solution and though I could share it here.

Lead collision allows to predict the path to follow in order to hit a moving target, and to calculate the impact point if needed. This can be useful for some video games, and can be used in both 2D and 3D. Only the target's position and speed vector, and the projectile's position and speed are needed.

Here is a video I made explaining the method using the intercept theorem (or Thales proportionality theorem) :

That’s some neat stuff perfect for a variety of homing missiles

While there is so few in space you still sometimes need some "collision avoidance" (if there is an obstacle between "missile" and "target").

Have fun adding that in - and bringing up a new video.


Aside of that I of course watched the full video and want to say "thanks".
