Okay, my camera is throwing up massive problems. I have 5 Objects on screen, and the camera should be positioned on the 3rd one. Logically, I'd expext this to show, all the models. However, it's just throwing up nothing. Anyone able to look over this code please? (It's only a test scenario right now, I'm just trying to sort the camera)

+ Code Snippet

REM LOAD PLAYER
	LOAD OBJECT "C:\Users\User\Documents\ZOMBIE 3d SIDE SCROLLER\Models\civilianmale.X", 1

REM LOAD ZOMBIES
	LOAD OBJECT "C:\Users\User\Documents\ZOMBIE 3d SIDE SCROLLER\Models\fatzombie.X", 2
	LOAD OBJECT "C:\Users\User\Documents\ZOMBIE 3d SIDE SCROLLER\Models\zombiecop.X", 3
	LOAD OBJECT "C:\Users\User\Documents\ZOMBIE 3d SIDE SCROLLER\Models\zombienurse.X", 4
	LOAD OBJECT "C:\Users\User\Documents\ZOMBIE 3d SIDE SCROLLER\Models\zombiesurgeon.X", 5

REM TEMPORARY POSITIONING
	POSITION OBJECT 1, 100,300,100
	POSITION OBJECT 2, 200,0,0
	POSITION OBJECT 3, 300,0,0
	POSITION OBJECT 4, 400,0,0
	POSITION OBJECT 5, 500,0, 0

1) use autocam off to take control of the camera. otherwise, the (default) autocam will focus on the last object loaded/created.

2) your make camera 1 call is actually creating a 2nd camera as camera 0 already exists. i don't think you realize this. a second camera doesn't appear necessary here. (you've also created a second light as light 0 already exists, btw)

3) while you may have positioned the camera near your intended target (object 3), you should follow it with point camera. since you postioned object 3 with:

POSITION OBJECT 3, 300,0,0

and want your camera positioned:

POSITION CAMERA 1,100,300,100

you would still want to:

point camera 300.0,0.0,0.0 `(your object 3's position)

to make sure the camera is pointing directly at object 3. this still won't show all the objects/models as you expect because:

1) you've placed the camera inside object 1 (based on your code)

2) it looks like you've got the camera placed too close to the "middle" object to ensure the other objects would actually be in view.

anyway, that's somewhere for you to start. take a look at all the camera (and light) help files for more info and begin experimenting. you'll get the hang of it pretty quick.

good luck!

Aah thanks, that's been a massive help and I think I've figured out what I need to do now. However, I can't see a problem with the code but it's still throwing up an undefined parser error, not entirely sure why.

Although unlikely the direct cause of your current problem I strongly suggest that you create folders for your projects and have a 'Models' folder inside each one (where required).

You can then replace:

LOAD OBJECT "C:\Users\User\Documents\ZOMBIE 3d SIDE SCROLLER\Models\zombiesurgeon.X", 5

with...

LOAD OBJECT "Models\zombiesurgeon.X",5

You might have problems later when you move your final exe to a new location if you use hard-coded paths.

Aah, I do have it almost like that.

Inside "C:\Users\User\Documents\ZOMBIE 3d SIDE SCROLLER\Code"
is where I placed the code - should this be moved to

"C:\Users\User\Documents\ZOMBIE 3d SIDE SCROLLER\"

Thanks for your response TDK, I'm finding this forum very helpful.
