A C64 Game - Step 81

A new pickup! And it shines

Sometimes one of those wondrous bullets of Samuel Colt will be dropped. Those can kill any enemy with one shot, so use them well!



The changes are quite simple. In the PickupItem routine we add a handler for those new items:

                  cmp #ITEM_SUPER_BULLET
		  beq .EffectSuperBullet

We make sure only Dean can use it and increase the super bullet counter:

.EffectSuperBullet		 
		  cpx #1
		  beq .SamDoesNotUseBullets
		 
		  inc SUPER_BULLET

The super bullet shot will flash red instead of white, so we add:

		  ;red flash for super bullet
		  lda SUPER_BULLET
		  beq +
		 
		  lda #2
		  jmp ++
		 
+		 
		  lda #1
++		 		  sta VIC_BACKGROUND_COLOR

and finally, at the enemy shot routine we add

                  lda SUPER_BULLET
		  beq +
		 
		  ;directly kill enemy
		  dec SUPER_BULLET
		  jmp .EnemyKilled
		 
+		 
		  lda SPRITE_HP,x
		  dec SPRITE_HP,x
		  lda SPRITE_HP,x
		  beq .EnemyKilled

Done!

BTW, the super bullet also works on bosses!
