Simple physics sample

[Valcriss]

Like i was playing with physics, i made a little sample...

Played with your render loop a little bit to make it run smoother.  The ball was like blinking around the screen.  Thought that to be a little odd. It felt like the ball was on 2400bps connection playing quake.  Reason i moved manageinputs out is because once we start rendering we want to finnish it asap. Text calls should also be called last not in the middle.  And i have no clue why but it got even better when i changed the simulate to not be based off AccurateTimeElapsed.  I assume that do to the fact that accurate time is based off time between frames that, it also has to do with frame rate being above normal.  Aka over 50 fps, this sample runs in the 1500 fps mark on one of my machines.  I have yet to play with phyics but i learned alot from your code.  Anyone else have insight on this call to Simulate?  I have been wanting to play with it myself.

 _scene.SetBackgroundColor(0, 0, 0);
            while (_doRender)
            {
                ManageInputs();
               
                _engine.Clear();
               
                // _physics.Simulate(_engine.AccurateTimeElapsed());
                _physics.Simulate(.1f);
                _scene.RenderAll(false);
                _scene.FinalizeShadows();
                DrawText();
                _engine.RenderToScreen();

               
                Application.DoEvents();
            }

Thx for reply ShiZZa_AuX, i will update my sample project ASAP.

Normally you have to update with   _engine.AccurateTimeElapsed() / 1000.
Since the update step is in seconds

Thx Sylvain,  

I have updated my sample using ShiZZa_AuX and Sylvain's comments, and set physic's values to something more realistic i think.

I converted that Physics sample over to VB6 if anyone is interested:

Don't forget you can upload samples in the resource section of the site !
We will approve them and then they will be always on this site and not lost and spread on 43543 sites eh
