Short: Smooth intuiscreen scroll OS3.0 (Asm) Author: mares1@menza.mff.cuni.cz Uploader: mares1 menza mff cuni cz Type: dev/src Requires: OS3.0 Architecture: m68k-amigaos This is example how to scroll intuition screen via graphics.library/ScrollVPort in multitasking friendly way. CPU usage = 9% on 68030/50MHz, 50% on plain A1200 in 640/512/256col. Yes, it could mean that 2 players with 2 joysticks can play 2 FuperFrog-like games on one amiga simultaneously ! ( Plus raytrace on background ! :) In order to run enclosed exe you will need lowlevel.library, Joystick, asl.library, AGA or better and 512KB of chip ram, but scrolling system needs OS3.0 ONLY and nothing more.
