limits in games

[metal_hed]

i built an etch-a-sketch game and u want to know how to set a limit the line can goto...like a boarder.

[Tony]

you compare current position to 0,0 and maxx,maxy to see if you're still inside the boarder or not

[AsianSensation]

or you could use whatdotcolor. (I'm only filling in for dodge here )

[jonos]

you can't keep the mouse in the run window in turing (at least im pretty sure), but you can make it so it doesn't draw outside of the border:

if mousex >= maxx or mousex <= 0 or mousey >= maxy or mousey <= 0 then
don't draw anything
else
let the person draw something
end if

[the_short1]

for whatdotcolor (since nonoen release explained)


draw a border around to outside..
drawbox (0,0,maxx,maxy,color of your choice)
then
if whatdotcolor (the position of the line) = the color above
U hit wall...
else
u can keep going

try to make that color of border something realy unique like maybe 155 or something... see my color chart HERE for full color list
