Side of a collision

[davidzx]

Hi,

Is there an ASM way to get the collision side between two sprites? I mean, if sprite1 is collisioning with sprite2 by right, left, up or down. Comparing x, y variables beetween the two sprites is a mess.

Thanks

Hi!
Some such asm code would really be interesting.
I really don't know if there is. For now, I would do as you say.

In sprite one
LET I Y

In sprite two

IF HIT (sprite one)
IF I > X
(...)
ENDIF
ELSE
(...)
ENDIF

Cheers, fellow!!

Hola Paco, thanks for your reply

I'm using x, y coordenates but I'm having issues when sprites collision corner to corner. Because sprite moves every two pixels it's not clear to me which side of the corner has impacted with the other sprite

There is .... however you do have to set the DIRECTION variable for SPRITE2.
If you want the collision side of SPRITE1 which collides with SPRITE2

EVENT SPRITETYPE1
...
IF COLLISION 2
OTHER
LET I DIRECTION
ENDSPRITE
IF I = LEFT
; Collision side right
ENDIF
IF I = RIGHT
; Collision side left
ENDIF
IF I = UP
; Collision side down
ENDIF
IF I = DOWN
; Collision side up
ENDIF
ENDIF
...
