Hi,

I'm trying to precalculate where an object will be in the future, knowing it's speed, mass and direction, without the scene changing.
Essentially how it's often used in other games to show what path a hand grenade is going to take if it's being thrown with a certain speed and angle.
It would then follow exactly this path when it's released.

Since the present scene should not be changed, I would somehow have to precalculate the physics in the background and only the particles showing the path have to update when the variables change.
The way I'm going to use this the physics in the "present" would not change, so the game is actually paused and only the camera can move around, the variables can be changed and the particles adjust.

I've worked with Gamestudios native physics engine and looked into Newton a bit, but I don't see how I could get this to work. I think I'm going to go with Newton though, because the calculations would have to be very precise.
If two paths show that the two object will collide at a certain point in time and space, they would collide just like that afterwards.

Has anyone got a good suggestion where to start with this?

so long...
