Tunnel

Description:This is the official release of the Prime port of the 39gII Tunnel clone written in BASIC, now adapted for the larger screen and color display. This new version adds speed throttling to ensure that the game runs as close as possible to the same speed as the original Prime on both the emulator and G2 hardware revision of the calculator. It is probably the first ever game ever made available for download for this calculator model. It isn't meant to show coding skills, especially considering the game was made before the author's knowledge of the DIMGROB_P and BLIT_P commands (although an intro transition using them was added afterward), but as you'll see on-calc, even if the entire screen content must be refreshed every frame, it still gets a high frame rate, because of how incredibly fast the calculator is, even with redrawing the entire screen rectangles and score text every frame. As for the multicolor and 3D-ish text effects, they are possible because the HP Prime lets you use text with no background, so all you have to do is superpose multiple copies of that text, gradually changing its color and position through a FOR loop. This also lets you use bold text. To play, just use the UP and DOWN keys and quit with ON.
