i made a textdraw to show the exact amount of the players health,

Code:

new Float:he;
GetPlayerHealth(playerid,he);
new string[40];
format(string, 40, "Health: %f",he);
TextDrawSetString(Textdrawhealth, string);
TextDrawShowForPlayer(playerid,Textdrawhealth);

But how do i make it automatically update?

Get the player's health again, and reset the text draw.

You'd have to create a function and put that function on a timer, for example:

pawn Code:

forward DrawNewHealth(playerid);
public DrawNewHealth(playerid)
{
    new Float:pHealth, string[128];
    GetPlayerHealth(playerid, pHealth);
    format(string, sizeof(string), "Health %f", pHealth);
    TextDrawSetString(TEXTDRAWNAME, string) // this is where you would update the actual textdraw
    return 1;
}

Then set that on a timer whenever you show the textdraw, maybe OnGameModeInit?
