LUA Hack Help

Hey guys,

So I am new to gmod lua coding and this tread will probably sound a bit noobish to you guys but I figured it will make my life a while lot easier if I just ask someone instead of continuing trying to work it out myself.

1. I can make a Name esp or whatever just fine, that is pretty easy. But if I try to draw two different ESP's to the screen (e.g. Name tags and Distance) they over lap each other and stuff like that, how do I make it so they draw the same size and in the same position relative to the player no matter where I am standing. (I have tried looking through other hacks for the answers but I am new to this shit and the hacks I looked through uses these values thingies and I just get really confused by, idk, but yeah, can someone please explain how to do this, and maybe even past simple ESP code that just draws 2 items on the players so I can see how it is done). I know the following pictures are shit quality and and the font is bad and what not, but hopefully you get what I am trying to say... so ESP1 is what it looks like when I am close up, and ESP2 is what it looks like from a distance, I know it is hard to see, but the two items get drawn over each other.




2. I can make an aimbot (it is super shitty, but you know, it works) but I can't work out how to make a line of sight checker (so basically my aimbot aims at people even if they are behind a wall). After failing at working it out myself I tried copy pasting some code from a different hack (I am preparing for some flame here :P) and it works as expected, but if I am close to the player the aimbot will just turn itself off (as if I was behind a wall).
So basically I am asking why that happens, and can someone explain how to make a line of sight checker (or even post code that is ONLY an aimbot with a line of sight checker (very simple so I can understand) so I can read through it and see how they are made).

Thanks guys and sorry again for the noobyness of this post :P

EDIT: I have half worked out the line of sight checks, it does what it's meant to do (it only aims at people if they are visible), so basically my aimbot aims at the closest person to me. So if I it is aiming at someone then I go behind a wall and no one else is visable it will stay aiming at that person. But if I go behind a wall and there is a different person visible it will lock onto that other person. I understand why this is happening, but I am kinda lost on how to fix it, so yeah, help please :P (still need help with the ESP as well)
