Animation more fluid?

[kecos]

I'm working on a simple game, and I need help with making the animation more fluid. The way it's set up now, if I hold a key, it moves once, freezes, then moves fast. Is there any way I can just make it move at a set speed while the key is held down?

Here is the code for using the up arrow key to move the character up:

        Clock.Interval = 40;
        if (keyEvent.KeyCode == Keys.Up)
        {
            keyLastPressed = 2;
            if (y > -10)
            {
                y -= 10;
            }
            Invalidate();
        }

Try placing your code in the KeyDown event.

Also, you may want to read about double-buffering to optimize rendering operations. One technique is to draw first on a memory resident buffer (eg bitmap), then render the image to the screen (eg form).

Agreed, keying off the key-pressed/released events will be better than relying on the O/S to fire multiple keystroke events. Regarding the double buffering, I've had best results by running two threads, one controlling the model and one controlling the rendering. Basically you have a handle to the model. The model thread writes a temporary model and then updates the handle. The rendering thread performs the graphical double buffering, keying off the model handle. This approach divorces your logical execution speed from your FPS.
