Fire up the Bitmap menu and change the bitmap to SHIP.TGA, a simple raytraced spacecraft viewed from its rear end. To use this effectively, it will need to travel forward into the distance. This means that our ship.tga object will only appear between frames ten and sixty. The computer will not bother plotting it for 1 to 9. Our next to last task is a comet.
Comets consist of two parts, a tail and a coma.
The tail can be LHS or RHS and the coma is the brightest part of the comet, the nucleus. We will make it go from right to left this time. This will make a tail appear to stream out from the nucleus towards the left hand side of the screen. It will start life at 150 pixels long. Since we want it off screen to the right, the centre will be about 75 pixels past the edge, about 395.
