Making a body start and stop faster

[Rick]

I'm using some spectator code that I found around the forum that uses a body sphere to move the camera around. I like this because I want totally free camera movement, but I would prefer more precise movement. Currently the sphere takes awhile to come to a rest. When I let go of the movement key I would prefer it instantly stop. How can I achieve that?

 

       // setup code 
       TBody spectator = CreateBodySphere();
       SetBodyMass(spectator, 50);
       SetBodyGravityMode(spectator, 0);			// disable gravity for this body
       SetBodyDamping(spectator, 500.0);
       EntityType(spectator, 3);
       SetBodyBuoyancyMode(spectator, 1);
       PositionEntity(spectator,Vec3(0,5,-10));
       mx=Curve(MouseX()-GraphicsWidth()/2,mx,5);
       my=Curve(MouseY()-GraphicsHeight()/2,my,5);
       MoveMouse(GraphicsWidth()/2,GraphicsHeight()/2);

// main loop code
       camrotation.X=camrotation.X+my/10.0;
       camrotation.Y=camrotation.Y-mx/10.0;
       RotateEntity(cam,camrotation);

       move=KeyDown(KEY_W)-KeyDown(KEY_S);
       strafe=KeyDown(KEY_D)-KeyDown(KEY_A);
       TVec3 force = Vec3(strafe * 200.0,0,move * 200.0);
       force = TFormVector(force, cam, 0);
       AddBodyForce(spectator, force);

       PositionEntity(cam,EntityPosition(spectator));

You can add a active break system and adjust the break factor:

	if( (move==0 && strafe==0 && jump==0 && autobrake) || KeyDown() )
{
	TVec3 vel=GetBodyVelocity( pla->body );
	vel.X=-vel.X*2;
	vel.Y=-vel.Y*2;
	vel.Z=-vel.Z*2;
	AddBodyForce( pla->body, vel );
}

Sweet that works! Thanks.

Don't move the camera by "Forces" ....

To get the physics to work with collisions on bodies (which is something I want) I have to move the bodies by forces don't I? I can't use anything else or it'll break the physics right? That's my understanding of it anyway.

[Marleys Ghost]

what exactly are you trying to do?

[Rick]

Move the camera around, but have it collide with bodies. I just needed the camera to stop faster because I dislike the sliding movement that was happening. Lumooja's code solved the issue though so it's all good.
