Hello World,

I have a cube, textured in blender using 2 textures, 1 on top, and 4 on the other sides. The file is saved to the desktop exported as a .x file.
When I dont make a camera at all, the background is black but i can see my object fine, and perfectly textured.
When I add a camera, no matter where i position it, the object doesnt appear (or appears really far away) and the background is green no matter how i color it. whats wrong??

+ Code Snippet

sync on
sync rate 60
backdrop on
color backdrop 100
load object "C:/Users/Brett/Desktop/grass.x",1
scale object 1,20,20,20
position object 1,0,0,0
x = object position x (1)
y = object position y (1)
z = object position z (1)
make camera 1
position camera 1,0,0,-50
do
    sync
LOOP

Why are you using camera 1? Camera 0 already exists

This just happened to me too.

I've never had a problem with it before, and suddenly whenever I create another camera, I can't see the object in its viewport. Which is REALLY weird because it used to work just fine.

Sorry that I can't help you CocaCola. I've been trying to find a solution to it and there doesn't seem to be one.

What version of Windows are you using?

That's odd; your code works for me when I use MAKE OBJECT SPHERE or load Miko.x (a model that comes with DBPro).

As for the background problem, it is possible to specify a camera number in the COLOR BACKDROP command. So if you put your COLOR BACKDROP after the second camera is created and set the optional camera number parameter to 1, then your backdrop should be colored properly on camera 1.

It kind of works for me. I've discovered it seems to be related to the Set Camera View (CamNum) command...odd.

setup:
     //Set the display mode

     //Set window size, title and position
     set window size 960,720
     set window position 100,0
     set window title "A.L.E Level Editor v0.01"
     //Set the sync rate
     sync on 
     sync rate 90 : //Not too fast, not too slow
     
     position camera 0,160,0
     xrotate camera 90
     set camera view 800,0,224,224
     
     make camera 1
     position camera 1,0,5,-30
     set camera view 1,0,0,800,600
     color backdrop 1,rgb(0,15,255)
     
     make object cube 1,5
     position object 1,0,0,0
return

Still have no idea why it doesn't work.

CoffeeCoder, add the "backdrop on" just to make sure.

@CocaCola:

That didn't work.

I am totally stumped.

Another odd thing is that it seems to be on this project only, not any other ones. So maybe it's a setting somewhere?

It sounds to me like you can see the object with camera 0 due to autocam, but can't see it in camera 1 because that's created afterwards.

Also, you need to make sure that your camera screen coordinates don't overlap, or you may get some strange results.

Is this what you intended?

+ Code Snippet

     //Set the display mode
     set display mode 1024,768,32
     //Set window size, title and position
     set window size 960,720
     set window position 100,0
     set window title "A.L.E Level Editor v0.01"
     //Set the sync rate
     sync on 
     sync rate 90 : //Not too fast, not too slow
     autocam off
     position camera 0,160,0
     point camera 0, 0, 0
     set camera view 800,0,1024,224
     
     make camera 1
     position camera 1,0,5,-30
     point camera 0, 0, 0
     set camera view 1,0,0,800,600
     color backdrop 1,rgb(0,155,25)
     
     make object cube 1,5
     position object 1,0,0,0
do
sync
loop

Camera 0 is a long way away from the object - reduce it's y coordinate to make it closer.

Thanks Green Gandalf, that worked! I can see everything perfectly!

I totally forgot about the "autocam off" command. That should have been my first thought.

Oh, and the camera is far away from the object because I need a "level map" and had to position it far away enough to show a decent amount of objects.
