A C64 Game - Step 65



4: Adsense

I had several complaints as there was no bullet. Well, after this step there is still none, but you do get a flash Posted Image

When shooting we add this:

		  lda #5
		  sta PLAYER_RELOAD_FLASH_POS
		  lda #1
		  sta VIC_BACKGROUND_COLOR

Below the call to ObjectControl we add this snippet to update the flash via the color fade table:

;shot flash
		  lda PLAYER_RELOAD_FLASH_POS
		  beq +
		
		  dec PLAYER_RELOAD_FLASH_POS
		  lda VIC_BACKGROUND_COLOR
		  and #$0f
		  tay
		  lda COLOR_FADE_OUT_TABLE,y
		  sta VIC_BACKGROUND_COLOR
		
+


And the color fade table itself:

COLOR_FADE_IN_TABLE
		  !byte 11,1,10,1,10,13,14,1,7,8,1,12,15,1,1,1
COLOR_FADE_OUT_TABLE
		  !byte 0,15,9,14,6,6,11,10,9,11,2,0,11,5,6,12
