Can anyone help me with a bit of script modifying?

Question

Hey guys, can anyone help me?
Here is some script that makes my character obviously move
and detects walls. I would like to modify the script so that when
my character hits the right keydown, the sprite changes to cast
member "right". I have tried and so far all i have done is succeed
in making the cast member change but this then deactivates the
walls. Any ideas??
on exitFrame me
if keyPressed(123) then
move(me,-5,0)
end if
if keyPressed(124) then
move(me,5,0)
end if
if keyPressed(125) then
move(me,0,5)
end if
if keyPressed(126) then
move(me,0,-5)
end if
end
on move me, dx, dy
oldRect = sprite(me.spritenum).rect
newRect = oldRect + rect(dx,dy,dx,dy)
hitWall = FALSE
repeat with i = 2 to 30
if sendSprite(i,#hitWall,newRect) then
hitWall = TRUE
exit repeat
end if
end repeat
if not hitWall then
sprite(me.spriteNum).loc = sprite(me.spriteNum).loc +
point(dx,dy)
end if
end
Many thanks.

Hi Hayz,
I actually recognise that script.
Try the following:
on exitFrame me
if keyPressed(123) then --left
move(me,-5,0,1)
end if
if keyPressed(124) then -- right
move(me,5,0, 2)
end if
if keyPressed(125) then -- down
move(me,0,5, 3)
end if
if keyPressed(126) then -- up
move(me,0,-5, 4)
end if
end
on move me, dx, dy, directionMove
-- get rect and add change to it
oldRect = sprite(me.spriteNum).rect
newRect = oldRect + rect(dx,dy,dx,dy)
case directionMove of
1: (sprite(me.spritenum)).member = member("character_left")
2: (sprite(me.spritenum)).member = member("character_right")
3: (sprite(me.spritenum)).member = member("character_down")
4: (sprite(me.spritenum)).member = member("character_up")
end case
-- loop through possible wall sprites and detect collisions
hitWall = FALSE
repeat with i = 2 to 30
if sendSprite(i,#hitWall,newRect) then
hitWall = TRUE
-- insert collision instructions here
exit repeat
end if
end repeat
-- if no collision, then move sprite
if not hitWall then
sprite(me.spriteNum).loc = sprite(me.spriteNum).loc +
point(dx,dy)
end if
end
And remember, the sprites that you're colliding with need
their own behavior with:
on hitWall me, objRect
if intersect(sprite(me.spriteNum).rect,objRect) <>
rect(0,0,0,0) then
return TRUE
else
return FALSE
end if
end
