hfliptile must be called every vblank?

[Deleted]

It seems like I must " propsprite object_sprite,index_sprite+hfliptile(1),0" every vblank. If I take the propsprite out of vblank the sprite does not appear flipped.

Is there a way around this? Seems like it would be a drain to have a propsprite every vblank for every sprite that may be flipped.

Nope .. it's persistent. Below is proof ( D-Pad moves the sprite, B button flips it ).

x = 284
y = 236

s = addsprite(1,1)
propsprite s,57,0
movesprite s,x,y

on vblank gosub main
enable interrupt vblank
end

main:
l = j
j = joypad()

x+= j.3-j.2
y+= j.1-j.0

if j.4 AND l.4 = 0 then
f = 1-f
propsprite s,57+hfliptile(f),0
endif

movesprite s,x,y
return

Yeah, thanks for the sanity check. I just confirmed it myself.

Very, very strange. I guess I need to be more observant of the times when I think it is reverting back to a non-flipped state. sigh.

look at your code, there might be something that changes the sprite back to his non-flipped state
