Is there a script or something that can make a sun rise and set? Also like every 10 mins mars would show? Thanks in advance.

This is actually quite simple. I made a script for this and then ditched it for the time until I needed it, later I'll see if I can post it.

Here is the sun rise/set script.

code:

---

 // Starting of sunset code

function day_pass() {
	 sun_angle.tilt = 0.2;
	 while (1) {
	       sun_angle.tilt += 5 * TIME;
	       if ( sun_angle.tilt == 90 && sun_angle.pan == 0 ) {
		    sun_angle.pan = 360; }
		    else
		    { sun_angle.pan = 0; minutes_to_mars += 1; }  // Every time this happens add a 1 to the variable minutes_to_mars, you would have to slow this script down a LOT though, right now it is sped up for testing purposes
/*then add this*/ if ( minutes_to_mars >= 10 ) { mars.visible = on; } else { mars.visible = off; }
	       wait(6);
	       }
	  }

// Ending of sunset code 

---

With a few tweaks to that you could easily get the Mars thing going. Read the comments I've added to the code for examples.

I'm sorry, this is probably not a very clean or efficient script but it will probably get the job done till you learn to script, assuming you'll take the time to (it really is worth it 'cause then you can have FUN [yes, I said it is fun] making stuff happen).

Thanks but what file do I edit? is it the file name.wdl?

You can either make this in a seperate WDL file or you can add it to your level's main WDL file.
