Hi everyone,
I have a quick question on how to get 2-D objects (like a basic circle) move across the screen using arrowkeys. I think I have an idea on how to do it but I'm not sure. If you could be give me a code and an explanation that would be AWESOME.

Thanks!

If you have an idea, post it up.

Much better to say how you think you would do it and have it corrected than to just get people to give you the answer straight away.

well maybe this will work if you put it in your game



Put that in your do,loop command, change "spritenumber" with your sprites number.

Here's kind of how it works


that is defining a variable (x and y) that it is the same thing as your sprites position x and y. (it's just a shorter way of doing things)


this is saying if you press one of the arrow keys then...


for an example of that lets only do x=x+1
that is saying that object position x is equal to object position x but your adding one to move the sprite


That is simply moving your sprite to the new position.

The simplest way I know is this.

Obviously you need to set up x and y unless you want 0,0 as the first point. Put the code in a subroutine or function and call it from your main loop.
