keyboard scrolling

heya. i recently was sorta making an attempt to make a game but I've already hit a roadblock (lol)

I've got mouse scrolling working with tutorials found in the forum, but I can't seem to be able to get the keyboard scrolling to work - like in RTS where you can press arrow keys to move your screen around.

I've currently set 'the key - is down' and it is instructed to perform 'system: scroll to x 10', but instead of scrolling incrementally, it just warps to x10 coordinates. how can I set the math to work incrementally?

also, another question if you don't mind. is it possible to attach RTS behavior sprites to other sprites so their movements are constricted? like a road, for example. (instead of going through pesky pathfinding.)

thanks!

You need to retrieve the current scroll value. So instead of scroll to X 10, it should be scroll to X ScrollX + 10. ScrollX will retrieve the current X scroll value; likewise, ScrollY will retrieve the current Y scroll value.

Also, I don't there's a way to do anything like the second question you asked(not in the behavior, anyways). You'd have to come up with your own method of doing that.

woot! thanks. that solved my scrolling problem. I'll try to think of something for my second question... perhaps i am to wait for path implementation.

Use Time Delta for smooth scrolling!

+Key Right is down

Scroll.X=Scroll.X+20*TimeDelta (use a higher multiplier for faster scrolling)

awesome, thanks!
