I am sorry if the problem was faced in other topic, i didn't find anything useful!

I have a 1024x768 scene, it's a "between-levels" map, where the player can choose where to go by clicking places.
The problem is that the background image is 1900 pixel wide, and i have to scroll right and left the map to view all the scene.

This task is automatically done by engine when the actor walk around...but what if actor is not loaded? How can i achieve this?

thank you very much!

You can check cursor location (Scene.MouseX() and Scene.MouseY()) and manually scroll the scene with Scene.ScrollTo(X,Y).

Wow, i love wme, i've missed that function
thank you!

I wrote code that looks very good for this task, scrolling a wide scene from left to right (and viceversa), when the cursor is positioned at the edges of the screen.

If anybody need, just ask

Can someone post a small sample project with this code? Been curious about how to do this for awhile 

[Ennio]

Sure!
As I said above, in my project i needed a navigable map so the actor, inventory, and other things like these are made inactive in the scene_init script, where i also attach another script, which i called navigation.script and which i detach when player leaves this scene

Here's code for navigation.script (note, the game window is 1024x768, this scene 1900x768)

Code: WME Script

1. //set MainObject to null because i don't need in my scene the camera follow the actor
2. Game.MainObject = null;
3. //change the scroll speed, default were too slow for me
4. Scene.ScrollSpeedX = 0.5;
5. Scene.ScrollPixelsX = 2;
6.  
7. NavigationScroll();
8.  
9. function NavigationScroll()
10. {
11.         while(true)
12.         {
13.                 if (Game.MouseX < 20)
14.                 {
15.                         Scene.AutoScroll = true;
16.                         Game.SetCursor("sprites\system\mapLeftArrow.sprite");
17.                         Scene.ScrollToAsync(0, 0);
18.                        
19.                 }
20.                
21.                 else if (Game.MouseX > 1004)
22.                 {
23.                         Scene.AutoScroll = true;
24.                         Game.SetCursor("sprites\system\mapRightArrow.sprite");
25.                         Scene.ScrollToAsync(1900, 0);
26.                 }
27.                
28.                 //if mouse position is not at the screen edges, stop scrolling and return to standard cursor
29.                 else if (Game.MouseX > 20 && Game.MouseX < 1004)
30.                 {
31.                         Game.SetCursor("sprites\system\standardCursor.sprite");
32.                         var ex = Scene.MouseX;
33.                         var eps = Scene.MouseY;
34.                         Scene.ScrollToAsync("ex","eps");
35.                         Scene.AutoScroll = false;
36.                 }
37.                
38.                
39.         Sleep(30);
40.         }
41. }
42.
