I want to make some kind of target cross or whatever you call it, in textdraw form,. It requires some advanced math and i suck at it. It should create textdraw on certain players head with reference to another player screen. If a player is present on my screen, a textdraw should be created on my screen at the position where the player is visible on my screen? How to do it? 3d to 2d

You mean:

pawn Код:

GetScreenPosFromWorld(forplayerid, Float:WorldX, Float:WorldY, Float:WorldZ, &Float:ScreenX, &Float:ScreenY);

this?

I'm in need of this too.
I just can't figure it out. :S
Guess we need FOV, Res or something like that..

Anyone expert in Maths/Trigonometry please help?

No idea, but i know you will need facing angle as well, for obvious reasons.

I think this would cause lag. And why do you need it? There are other ways of making things like this... For example: Attach a 3DTextLabel above players head with a label "TARGET", or something like that...

Exactly

It appears to everyone and it doesn't give the actual look like in fps games

I don't think it's possible to get the screen size, but it's possible to be made with GetPlayerCameraFrontVector with a timer and some basic trigonometric.

Anyone made this already, i suck at maths
