I suggest you add a dialogue box that pops up when you first open it. Donate $5 if you like the game. Good ol' shareware. 🙂

I was thinking a pop up that tells you to mail $5 along with a postage paid return envelope to send you a code to remove the pop up. Really keep it authentic.

I'll post another demo soon for anyone who is interested.

One thing I'm not quite sure how to deal with is overcoming the keyboard repeat rate which is set in the keyboard control panel. To start, I just went with the default keyDown and autoKey events to handle movement of the player character. The trouble with that is depending on how you set the repeat delay and repeat rate in the control panel, holding down an arrow key will either make the player movement very slow or very fast. I would like to control the speed of the player character, and also time movement with movement of other game mechanics.

What I have tried, with some success, is just setting the keyDown event to initiate continuous movement in the specified direction, and then used the keyUp event to stop all movement. This works quite well for achieving the speed and movement rate I want, but I've found it's very unreliable. Any key up event will stop movement entirely, so if you quickly switch between going up to going left, for example, and you hit the left key before releasing the up key, then releasing the up key will stop movement, even though you are holding down the left arrow.

OpenCPort(&offscreenCPort); /* Open colour offscreen port */
SetPort(&offscreenCPort); /* Set colour offscreen Port to current Port */
PortSize(256,256);
ClipRect(&offscreenCPort.portRect);
RectRgn(offscreenCPort.visRgn, &offscreenCPort.portRect);

offscreenPixmap = MakePixMap(256, 256, 4); /* create PixMap size of map */
SetPortPix(offscreenPixmap);
}

PixMapHandle aPixMap;

aPixMap = NewPixMap();

tempRowBytes = ((wantedDepth * (wantedWidth + 31) / 32) * wantedDepth);
