ok.. this is a great edit of my mini Script ^^
i edited it, so i only have 1 Function, but different handles to call the directions and sprites.

here´s the code:

My problem is..
When i start the script, the actor moves by itself to a direction.. but i hit no key...
What should he do?
1.) He must play the stand animation when no key is hitten
2.) he must play the walking animations when a direction key is pressed
3.) The size of the Window must be variable, because the stand sprite has a Framesize of 24 pixels... and the walk animations of 40 pixels...

In this Zip File are the Prite_Lines i used in that code:

Hope someone knows an answer to this... <a href="/Sonstiges/players_movement.zip" target="_blank">>>Click me<<</a>
IMPORTANT!!!: The Script in that Zip Acrhive is an older version.. so don´t loom at them ^^.. just at the Sprites if you want to try some thing with them.
