trying to change hud

Hello, i have questions what these line do



hudBuilder.createPictureNode Ah1zTVHud Ah1zTVLines 129 72 560 512

hudBuilder.createPictureNode Ah1zTVHud Ah1zTvHud -113 39 1024 512

hudBuilder.createPictureNode Ah1zTVHud Ah1zTVFrame 0 0 1024 1024

hudBuilder.createPictureNode Ah1zTVHud Ah1zTVCrosshair 274 183 256 256

hudBuilder.createPictureNode Ah1zTVHud Ah1zTVFeed 350 469 128 16

hudBuilder.createPictureNode Ah1zCoPilotHud Ah1zGunnerCross 369 269 64 64

hudBuilder.createPictureNode * * * * , and i cant see any effect changing them, i think only change i saw was, changing the Frame last two numbers, and saw effect ingame what it does, but no effect on any other, does it mean its hardcoded?

example there is alot of commands what can be explained like this: It's x/y/z and iirc when looking at the plane front on x is left/right, y is up/down and z is forward/back.

but how does hudBuilder.createPictureNode, i have 4 numbers i need to change, how can it be explained, sorry for noob question, i am confused.
