Hi. The first image is a 16x8 image I want to display, with a red shape, tan shape, brown shape, grey shape, app represented as a single sprite in a single 8x8 tile. I want to show it on my Intellivision display "packed" so the entire image fits into a single 8x8 area on the screen. The BASIC program makes what you see, kind of jumbled. Can anyone show me the right combination of constants and/or "magic numbers" to make the sprite stay in the middle of the screen within a single tile?

 

Thanks.

Remove ZOOMY2 to fit that entire image to 8x8 card. Each sprites is an 8x8 image as I can see the DATA.

• SPRITE 0,0+ x + VISIBLE , 0+y, SPR_RED + SPR36
• SPRITE 1,0+ x + VISIBLE , 0+y, SPR_TAN + SPR37
• SPRITE 2,0+ x + VISIBLE , 4+y, SPR_BROWN + SPR38
• SPRITE 3,0+ x + VISIBLE , 4+y , SPR_GREY + SPR39

Remove the constant number with a variable. From that bitmap, it should look like the bitmap provided. Using x and y variable with the number before or after will make the sprite as a group. Change the number before the x or y to change the offset of the meta sprite you're trying to put together.

x would be the screen width/2, so 80-4 to center it. So variable x=76. And variable y would be the screen height, I think 144/2, 72-4. So y=68. This may center the sprites in the center of the screen. So if you're using this sprite as your main character, I would rename the variable x and y to herox and heroy.

Thanks! I played with that a bit and got it.

 

Follow-up: is there a way to make the background of the MOB black, or should I make the foreground color of the BACKTAB black? I don't want any color except for black to show through on the tile where this is displaying.

 

Thanks again.

Make a fifth MOB with all the bits on and have it be black color, DATA $FFFF,$FFFF,$FFFF,$FFFF

MOBs get a single color: Foreground. Their background color is "transparent" (i.e., whatever is behind them in BACKTAB or other MOBs) always.
