New game: Earthraid

[LCD]

How do you do the water effect??!!

Awesome ¡¡

I was wondering the same!

I used Britlions Putchars and two counters for animation frames: one for water (8 frames) and one for mollusks (4 frames), then scanned the playfield. Everytime a water or mollusk was detected, the tile was redrawn with new frame of animation. There was also a sup which redraws on a mask, to not let the helicopter or missile flicker over mollusks or water, as Spectrum has no sprites. I also though about a possibility to use a second screen to eliminate any flickering and tearing, but I wanted to make the game playable on Spectrum 48K.
So for the speed of graphics I credit Britlions PutChars routine.
I hope to show with this game on WOS how fantastic ZXBC is, and get more users who will use it. And to demonstrate the speed of development I released two games at same time.
