Hello, I'm using DP to simulate a projectile in my game, and I would like to simulate a wind effect. If I apply a linear force to the projectile, rather than bend towards the direction the wind is moving, it just heads the same direction as the wind. (Without any bending) If I apply a linear momentum force, the same happens. If I apply angular force/momentum the projectile just stops in mid air and no longer moves.

What am I doing wrong!?

I use this method to apply the initial force to start the projectile moving:


And this is what I'm using to apply the wind force:

Hi Mobiius,

You are not applying forces, you are directly setting velocities and momentums manually, this invalidates and overrides the simulation solver.

You should have commands like PhyAddForce() or PhyApplyForce().
Remember that wind must be applied each frame so it will be a very small value compared to the initial force that moves the projectile.

Thank you for taking the time to reply.

Phy Add Rigid Body Force At Local was the command I needed.

Thanks a bunch for your help.
