Total Posts: 612 | Ok I was wondering how the code would look for an engine when scrolling in 2 directions. The example that's included in the documentation looks pretty good but it doesn't really help with boundary questions when using 2 directions. Like what to do if a character was at a said position. 4 would also help. Basically I'd appreciate any info on 2 directions.

X //char X cord
Y //char Y cord
L1 //X cord of special objects
L2 //Y cord of special objects
:Code:
For(Z,1,length(L1)
If (X= sub(L1,1,Z)) and (Y= sub(L2,1,Z))
prgm(seprate program or Goto that take you to a place where it decides what to do - DONT put this code in your move engine becasue it will slow it down)
:End Code:
Is this what you are asking about?

Total Posts: 583 | hmm i did this, if your talking about the same thing.
when you press left, then the screen moves left, yes?
screenvarX==B
screenvarY==A
mapvarX==D
mapvarY==C
screenvar, placement on screen
map var, placement on map
maxXvar==F
maxYvar==E
minXvar==H
minYvar==G
on the display map, you can tell it to display a certain sector of the map, tell that sector to move with this:
x=2 is press left button btw
real(8
Ans->X
if X=2
then
if B=8 and H!=4
then
H-4->H
F-4->F
end
if B<=8 and H<=4 and B!=0 (<= is less than or equal to)
B-4->B
if B>8
B-4->B
end
its a bit long, but it doesnt lag that much. i used it once, and it worked surprisingly fast, for all four directions.
or at the if x=2
then make it goto a program such as "ML" or moveleft.
