Drawing a trajectory

[Leonidas]

Hi @sergey_ch,

I see two ways to do this:

1. If you are using a trajectory that can be described with a math equation, run it against a number of points and find the projected positions.

Take a look at this library that can do that for you for a number of trajectories:

Ballistics extension

[image] Project Live demo Sources on Github Grab me a coffee [image] This extension helps to answer one common question - “What impulse should I give to my projectile so that it would hit the target?” You can provide input values, like the speed of your projectile, or the maximum height the projectile should fly to, and the extension will reply you with the calculated impulse vector (or a few even). How to install: Simply drag and drop Ballistics folder from the project …

2. A more advanced way would be to run a second ammo physics instance that can consume your starting position/forces and you can step forward e.g. 1000 steps in a single frame. As it steps forward record each position, now you have your trajectory.
