pictures dissapering

this is my first game i'm making and i have it so that when you press right arrow a picture moves to the right.
but when I press the right arrow it just dissaperes

my code is:
Graphics 800,600

SetBuffer BackBuffer()

Global char=LoadImage ("char.png")
Global charx,chary

charx=0
chary=568
While Not KeyHit(1)

Cls
DrawImage char, charx,chary
While KeyDown(205)
charx=charx +1
Wend
Flip

Wend

The problem is you've misunderstood the use of while/wend.

Replace this:

While KeyDown(205)
charx=charx +1
Wend

with this:

If KeyDown(205) Then
charx=charx +1
Else If KeyDown(203) Then
charx=charx -1
EndIf

and that should solve your problem.

P.S. Post your code in code blocks in the future.
Forum codes are here clicky

Thank you so much and thanks for the tip too
