[SOLVED] rounding health value - DartakousLien - 03.07.2014

well, it's hard to explain, so, look at the image. the code is below. I don't understand, why is it rouding. Or it's normal?

this is the code i used with sampgdk 3.7, but i'm using sampgdk4, and it's the same... I thought the problema in the sampgdk version, but when i change a the error persists, i realized that not

Well, nevermind, i'm sorry about the topic. I tried the same code in pawn and get the same problem. To me it looks stupid, because we get a FLOAT point of damage amount, and the heath is counted like INTEGER, but ok!

here is the new code and another foto

pawn Код:

#include <a_samp>

new rgeral = 0;

main() {}

public OnGameModeInit() {
    SetGameModeText("Hello, World!");
    AddPlayerClass(0, 1958.3783, 1343.1572, 15.3746, 269.1425, 0, 0, 0, 0, 0, 0);
    return true;
}
public OnPlayerConnect( playerid) {
    SendClientMessage(playerid, 0xFFFFFFFF, "Welcome to the HelloWorld server!");
    return true;
}
public OnPlayerRequestClass( playerid,  classid) {
    SetPlayerPos(playerid, 1958.3783, 1343.1572, 15.3746);
    SetPlayerCameraPos(playerid, 1958.3783, 1343.1572, 15.3746);
    SetPlayerCameraLookAt(playerid, 1958.3783, 1343.1572, 15.3746, CAMERA_CUT);
    return true;
}
public OnPlayerCommandText( playerid, cmdtext[]) {
    return false;
}
public OnPlayerUpdate( playerid) {
    if (rgeral == 5) {
        new Float:health;
        new msg[128];
        GetPlayerHealth(playerid, health);

        format(msg, 128, "%f", health);

        SendClientMessage(playerid, -1, msg);
        rgeral = 0;
    }
    else {
        rgeral++;
    }
    return true;
}
public OnPlayerTakeDamage( playerid,  issuerid, Float:amount,  weaponid,  bodypart) {

    new Float:vida;
    GetPlayerHealth(playerid, vida);

    new msg[128];
    format(msg, 128, "%f, %f", vida, amount);
    SendClientMessageToAll(0x00FF00FF, msg);
    return true;
}

Use %.0f instead of %f

edit: never mind

Yes, it seems rather odd since the value seems to be saved in an 8-bit unsigned integer on the client side. Values over 255 overflow.
