Hello,

i?ve a little Problem.

first, here?s my Game_Player:

What i?ve done:
I made it, so the player can?t stand still.. he automaticely moves to the right if no button is pressed.

My Problem is:
If the player moves to the left, the screen scrolls left too.. But it must scroll to the right.

For what do i need it:
I need it for a Side-Scrolling Shooter Engine. ( Flying from the left to the right )

More Infos:
I use the
- New Mode7
- A Hit Showing Script ( numbers poping out of Events )
- The Item-Icon push Script from Tibuda ( V 1.01 )
- The Blur Effect Script
- An Anti-Event-Lag and Window to Fullscreen script
- An Event-clone Script
- A Code to save an Events size into Arrays.
- I?ve made an edit, so i can show endless more pictures via Call_Script.

Short Info what i need:
- A Way to scroll the Map to the right, while the player is moving. Doesn?t matter if the player moves right, left, up..diagonal..etc..
- If the Player hits an unpassable Tile on the Top or the Bottom of himself, he moves automatical to the right ( glitching ).


I hope someone can help me.

What I'd do would be to give the player an invisible tileset, put him in a different section of the map, and have an event that is set to automatically move to the right. The rest could be done with eventing or further scripting.

The Engine?s running with 30FPS.. on a 6000? Alienware PC.. if i make more Events than i?ve at the moment, the game sucks..

So i need a scripted method.
