First how do I make people's nametags white instead of yellow?

Second how do I remove blips on the radar appearing where people are?

I'm not that much of a complete newbie at scripting but I don't know those exact functions.

Answer to your second question

under your gamemodeinit

pawn Код:

ShowPlayerMarkers(PLAYER_MARKERS_MODE_OFF);

[Potmon]

On the wiki it says:

Код:

ShowPlayerMarkers(0);

both will work!!

To set a player's name/tag colour, use SetPlayerColor.
Example of usage:

pawn Код:

public OnPlayerSpawn(playerid) //Called when a player (re)spawns
{
    SetPlayerColor(playerid, 0xFFFFFFFF); //0xFFFFFFFF is also known as white.
    return 1;
}

If you do not understand colours yet, try reading this: https://sampwiki.blast.hk/wiki/Hex_colors
If you really cannot be bothered trying to understand it, go to: http://www.psyclops.com/tools/rgb/
then just choose/click a colour you want, and it will give you the code for it. For example, if I want red, I go to http://www.psyclops.com/tools/rgb/, then I click on the 'Red' box from the list of colours at the bottom. If the background turns into the colour that I am looking for, then I simply go to the 'Hex String' box, and copy the Hex Code that is given to me. In this case it will be: 'FF0000'. Then I add '0x' to the front of it, and get: '0xFF0000', and I want it in solid color so I add FF to the end of it, leaving me with '0xFF0000FF'. Now I can set my player colors to Red.

pawn Код:

public OnPlayerSpawn(playerid)
{
    SetPlayerColor(playerid, 0xFF0000FF); //Player is now red.
    return 1;
}

As for your second, like the above poster has mentioned, you need to place the following code under OnGameModeInit. Read here: https://sampwiki.blast.hk/wiki/ShowPlayerMarkers

Example:

pawn Код:

public OnGameModeInit()
{
    ShowPlayerMarkers(PLAYER_MARKERS_MODE_OFF);
    return 1;
}

Hope I've helped a bit :S
