how do you make a code so when you push an arrow key, an object moves exatly 80 pixles over then stops untill you press the arrow key again?

best thing to do is make a 'timer'

e.g.

do
time = time + 1
if time > 500
then (..move fast..)
(..else move slow..)
if time > 1000
then time = 0
loop

i think thats right, i cant think my brain has gone blank from the 6 month db break

I assume the object moves 80 pixels at a rate of one a frame, and it moves all the way with just one keypress.



That should do it, the code needs adjusting to suit your program. Basically:
If the upkey is pressed and the object is not currently moving, then set the distance to 80.
If the distance is greater than 0, then move the object and decrease the distance.
If the distance is zero and the upkey is not pressed then reset the object_moving variable so you can start again.

man you guys are clever...

--- code ---
if upkey() = 1 and upressed = 0
upressed = 1
move object 1, 80
endif

if upkey() = 0 and upressed = 1
upressed = 0
endif
--- code ---

OR (with variables)

--- code ---
if upkey() = 1 and upressed = 0
upressed = 1
X = X + newxvalue(X, object angle y(1), 80)
Z = Z + newzvalue(Z, object angle y(1), 80)
endif

if upkey() = 0 and upressed = 1
upressed = 0
endif
--- code ---
