Unfortunately, I cannot seem to make the indicator show up for visible sprites at the very top of the screen by changing the values at 'cmp #$0100' or 'cmp #$00E6', which would've been perfect for a specific level gimmick I have involving wigglers and wall springboards. I also noticed that for some reason, the indicator's X-offset is way out of place with right-wall springboard:

(the red SMB3 piranha plant part is the indicator, and '!yoff_above' = $D0)

I tried to check the springboard's sprite number (0x6C) like so, but to no avail:

    ; Find the indicator's X position (centered on the sprite's hitbox)
    rep #$20
    and #$00FF : lsr
    clc : adc $04
    sec : sbc $1A
	lda !9E,x
	cmp #$6C
	bne .norm
if !tile_size == $00
    sec : sbc #$0014
    sec : sbc #$0018

	bra .cont
if !tile_size == $00
    sec : sbc #$0004
    sec : sbc #$0008

	bra .cont
    sta $04

If anyone knows how to fix these two issues, I'd heavily appreciate it as it would be perfect for my level!

Tested with:
  • Mesen 2.0.0
  • Lunar Magic 3.33
  • UberASM Tool 1.6
  • SA-1 Pack 1.40

Works well. Has a lot of useful customization options in the ASM file as well.

One thing worth noting though is that like the player offscreen indicator, this UberASM code will only work when inserted to a level, not a gamemode, so you can not apply it globally to every level by doing so.

is it possible to make this work in a vertical level? instead of tracking the sprite vertically offscreen, it would track them horizontally.

I may add that option later on
