Hi again, I have a big problem that is annoying me in the race mode.

What you see in that pic is, that the nametag text goes up when you go far away, and thats the error im being annoying with, I want the nametag text to be over the health bar always, not go far when I move away.

This is my script

nametag = {} 
local nametags = {} 
local g_screenX,g_screenY = guiGetScreenSize() 
local bHideNametags = false 
  
local NAMETAG_SCALE = 0.3 --Overall adjustment of the nametag, use this to resize but constrain proportions 
local NAMETAG_ALPHA_DISTANCE = 50 --Distance to start fading out 
local NAMETAG_DISTANCE = 120 --Distance until we're gone 
local NAMETAG_ALPHA = 120 --The overall alpha level of the nametag 
--The following arent actual pixel measurements, they're just proportional constraints 
local NAMETAG_TEXT_BAR_SPACE = 2 
local NAMETAG_WIDTH = 50 
local NAMETAG_HEIGHT = 5

If someone could help me please.

I checked it fast so i dont really know if its right or not.. but i believe its from the sy-40 + offset in this:

dxDrawText ( _getPlayerName(player), sx-30, sy-40 + offset, sx, sy, tocolor(r,g,b,textalpha), textscale*NAMETAG_TEXTSIZE, "default", "center", "bottom", false, false, false )

so try this:

dxDrawText ( _getPlayerName(player), sx, sy, g_screenX, g_screenY, tocolor(r,g,b,textalpha), textscale*NAMETAG_TEXTSIZE, "default", "center", "bottom", false, false, false )

and see how it works.. and then edit your:

local sx,sy = getScreenFromWorldPosition ( px, py, pz+0.95, 0.06 )

to change position of the nametags.

Sorry for late response..

You could either use getScreenFromWorldPosition two times, one for nametags and one for healthbar, or do the same thing i did by using dxGetFontHeight and for healthbar position y, using sy + fontHeight*(anynumber).
