Can't get background to show

[Spastuscat]

I'm very new to this, but I've been able to piece together code from several
sources to get the basic functionality I want. But somewhere along the way
I've killed my ability to have a background texture show up. Can anybody take
a look at this code and tell me where my problem is? Sorry, it's a bit long.

Just a quick look. It seems that you assigned the "sky" background to the default camera and then made two new cameras. Could it be that you need to assign the background to your other cameras?

[Spastuscat]

That's what I figured, but how do I apply a background to a specific camera? The only code I've found requires an "index" instead of the name of a camera.

Hi Spaz, try

-- create backdrop texture from bitmap
backdropTexture = sprite(me.spriteNum).newtexture("backdrop",
#fromCastMember, member("sky"))
-- add backdrop to frontCam
frontCam.camera.addBackdrop(backdropTexture,point( 0,0),0)
