In Lesson 6 we will learn better programming techniques than lesson 5 to get the sprite moving up & down. And this time instead of just boring up & down movement we will produce a bounce effect. Lets get straight into the coding: 10 LDA #147 20 JSR $FFD2 30 LDA #00 40 STA 53280 50 STA 53281 60 LDA #255 70 STA 53269 80 STA 53276 90 LDA #02 100 STA 53285 110 LDA #03 120 STA 53286 130 LDX #00 140 COLOUR LDA #04 150 STA 53287,X 160 INX 170 CPX #08 180 BNE COLOUR 190 LDA #64 200 LDX #00 210 ...

Here's roughly what we need to do: Clear Screen Set up Sprite pointer Set up Sprite Colours & Mode Set up X & Y position of Sprite Move it Down Move it Up So lets write the code: 10 LDA #147 20 JSR $FFD2 30 LDA #00 40 STA 53280 50 STA 53281 60 LDA #255 70 STA 53269 80 STA 53276 90 LDA #02 100 STA 53285 110 LDA #03 120 STA 53286 130 LDX #00 140 COLOUR LDA #04 150 STA 53287,X 160 INX 170 CPX #08 180 BNE COLOUR 190 LDX #64 200 STX 2040 210 ...

Type in the following in Zeus, assemble it and run it. 10 ORG 8192 20 LDA #147 30 JSR $FFD2 40 LDA #82 50 LOOP JSR $FFD2 60 JMP LOOP This is the assembler version of the basic program. When you have assembled it, use: SYS 8192 from BASIC to run it. Again the screen will fill with the letter R, only this time much faster. The a ...
