Various kinds of movements

To simply move right,left, up, or down, you just have to tell your sprite to add or subtract from the x and y coordinates of the sprite.
For example:
(this isn't as long as it seems;it's mostly comments to make sure you understand it all the way.
if you already know how to do this, skip down to the next post on how to jump)

'****set graphics*****

Graphics 600,800,16 'fullscreen

'****variables****

Global x:Float=0 'x-coordinate variable
Global y:Float=0 'y-coordinate variable

'****start loop****

While Not KeyDown(key_escape) 'as long as you don't push the escape button, it will continue to make the loop

DrawRect x,y,10,10 'sprite = 10x10 square

'***input keys***
If KeyDown(key_left) 'if you want to say while key_left not down, you just say "keydown(key_left)=false

x:-1 'subtract one from x is now =to x; try changing the value of what you subtract x with.
EndIf

If KeyDown(key_right)

x:+5 'add to x; going right 5 pixels; notice the speed of going right compared to left
EndIf

If KeyDown(key_up)

y:-1 'this is going up 1; not down because if you look at the screen, 0,0 starts at the top left and is positive going down and right
EndIf

If KeyDown(key_down)

y:+5 'this is going 5 down; faster than going up
EndIf

If KeyHit(key_space) 'if you tap space; holding it down doesn't matter

x=300 'go to center;resetting what x and y equal
y=400
EndIf

Flip 'this is just drawing the program onto the screen: the rectangle
'cls 'take out the first appostraphe in order to uncomment the cls(clear screen) to see what happens
'******End loop******
Wend

'*******Done!!!!***********

Try it out with the "cls" behind the apostraphe first. Try to spell your name with it. Then take out the apostraphe and see what happens.
