How to loop through the textdraws? - Nonameman - 23.07.2010

Hey Guys!

I have many textdraws, and I want to make them all hideable with pressing LMB.
To do it, I have to loop through all the textdraws, and close all of them, because I think I cannot hide just the active one.

I've already made these lines:

pawn Код:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
if(RELEASED(KEY_FIRE))
{
for(i=0; i<MAX_??; i++)
{
TextDrawHideForPlayer(playerid, i);
}}
return 1;
}

What should I put in place of '??' ?

Thanks
Nonameman

You could save all of the textdraws inside an array and then use

pawn Код:

sizeof(AllTextdraws)

But you might not be able to do this with your experience, just a guess, no offence!

pawn Код:

new textdraw[5]; // How many textdraws you have :) (On top of your script)
//OnGameModeInit:
textdraw[0] = CreateTextDraw....
//and so on

//Where you need the loop:
for(i=0; i<sizeof(textdraw); i++)
{
TextDrawHideForPlayer(playerid, i);
}

Something like that :P

I have a better idea, that you might be able to do yourself.

Create a custom function that creates the textdraw and sets +1 to a variable

pawn Код:

TextDrawCreateEx(Float:x, Float:y, text[])
{
       TextDrawCreate(x, y, text);
       Textdraws =+ 1;
}

Note: if you use this method, you will need a custom destroy function aswell wich does -1
