Speedometer

[Urefeu]

Hello.

I, a few days ago, saw a speedometer that inftead to have the text to show the speed, had a real speedometer.

I mean numbers (0, 20, 40 ...) arranged in a circle and a needle that moves depending on speed.

If you know or have a way to do it, I take.

Thank you!

No, he doesn't need any hack to have the speedometer - it is a script, search around and you will find it.

Thanks.

My final code is this :

#include <a_samp>
#include <colors>

enum td
{
	Text:TDSpeedClock[13]
}

new TextDraws[td];
new Text:TextDrawsd[MAX_PLAYERS];

public OnFilterScriptInit()
{
	TextDraws[TDSpeedClock][0] = TextDrawCreate(496.000000,400.000000,"~g~20");
 	TextDraws[TDSpeedClock][1] = TextDrawCreate(487.000000,388.000000,"~g~40");
 	TextDraws[TDSpeedClock][2] = TextDrawCreate(483.000000,375.000000,"~g~60");
 	TextDraws[TDSpeedClock][3] = TextDrawCreate(488.000000,362.000000,"~g~80");
 	TextDraws[TDSpeedClock][4] = TextDrawCreate(491.000000,349.000000,"~g~100");
 	TextDraws[TDSpeedClock][5] = TextDrawCreate(508.000000,336.500000,"~y~120");
 	TextDraws[TDSpeedClock][6] = TextDrawCreate(536.000000,332.000000,"~y~140");
 	TextDraws[TDSpeedClock][7] = TextDrawCreate(567.000000,337.000000,"~y~160");
 	TextDraws[TDSpeedClock][8] = TextDrawCreate(584.000000,348.000000,"~r~180");
 	TextDraws[TDSpeedClock][9] = TextDrawCreate(595.000000,360.000000,"~r~200");
 	TextDraws[TDSpeedClock][10] = TextDrawCreate(603.000000,374.000000,"~r~220");
 	TextDraws[TDSpeedClock][11] = TextDrawCreate(594.000000,386.000000,"~r~240");
 	TextDraws[TDSpeedClock][12] = TextDrawCreate(585.000000,399.000000,"~r~260");
 	for(new i = 0; i < 13; i++)
 		TextDrawSetShadow(TextDraws[TDSpeedClock][i], 1);
	return 1;
}

public OnPlayerStateChange(playerid, newstate, oldstate)
{
	if(newstate == PLAYER_STATE_DRIVER)
	{
		for(new i; i < 13; i++)
			TextDrawShowForPlayer(playerid, TextDraws[TDSpeedClock][i]);

	  	TextDrawsd[playerid] = TextDrawCreate(555.0, 402.0, "~b~.");

	}
	else
	{
		TextDrawHideForPlayer(playerid, TextDrawsd[playerid]);
		for(new i; i < 13; i++)
			TextDrawHideForPlayer(playerid, TextDraws[TDSpeedClock][i]);
	}

	return 1;
}

public OnPlayerUpdate(playerid)
{
	new
	    Float:fPos[3],
	    Float:Pos[2],
	    Float:fSpeed;

	if(GetPlayerState(playerid) == PLAYER_STATE_DRIVER)
	{
		GetVehicleVelocity(GetPlayerVehicleID(playerid), fPos[0], fPos[1], fPos[2]);

		fSpeed = floatsqroot(floatpower(fPos[0], 2) + floatpower(fPos[1], 2) +
		 floatpower(fPos[2], 2)) * 100;
		 
		new Float:alpha = 640 - fSpeed;

	    TextDrawHideForPlayer(playerid, TextDrawsd[playerid]);
	    TextDrawDestroy(TextDrawsd[playerid]);
  		GetDotXY(548, 401, Pos[0], Pos[1], alpha, 32);
  		TextDrawsd[playerid] = TextDrawCreate(Pos[0], Pos[1], "~w~.");
		TextDrawLetterSize(TextDrawsd[playerid], 0.73, -2.60);
		TextDrawSetOutline(TextDrawsd[playerid], 0);
		TextDrawSetShadow(TextDrawsd[playerid], 1);
		TextDrawShowForPlayer(playerid, TextDrawsd[playerid]);
		
		new string[400];
		format(string, 400, "fSpeed : %f - alpha : %f - Pos[0] : %f - Pos[1] : %f", fSpeed, alpha, Pos[0], Pos[1]);
		SendClientMessageToAll(ORANGE, string);
	}


	return 1;
}

stock GetDotXY(Float:StartPosX, Float:StartPosY, &Float:NewX, &Float:NewY, Float:alpha, Float:dist)
{
	 NewX = StartPosX + (dist * floatsin(alpha, degrees));
	 NewY = StartPosY + (dist * floatcos(alpha, degrees));
}

I'm particularly interested in this part:

GetVehicleVelocity(GetPlayerVehicleID(playerid), fPos[0], fPos[1], fPos[2]);

		fSpeed = floatsqroot(floatpower(fPos[0], 2) + floatpower(fPos[1], 2) +
		 floatpower(fPos[2], 2)) * 100;
		 
		new Float:alpha = 640 - fSpeed;

	    TextDrawHideForPlayer(playerid, TextDrawsd[playerid]);
	    TextDrawDestroy(TextDrawsd[playerid]);
  		GetDotXY(548, 401, Pos[0], Pos[1], alpha, 32);

and

stock GetDotXY(Float:StartPosX, Float:StartPosY, &Float:NewX, &Float:NewY, Float:alpha, Float:dist)
{
	 NewX = StartPosX + (dist * floatsin(alpha, degrees));
	 NewY = StartPosY + (dist * floatcos(alpha, degrees));
}

The problem is that I find the speed a little faster ... With a bike, I get to 100km / h (again, the bikes, no matter).

Except that if such because, I remain at 50km / h, the speed is really slow ... So I try to reduce some of the counter.

If I chance '* 200' to '* 100', the counter is not going further than 140/160 km / h.

If I spend 320 to 640, the meter starts at 40 ...

In short, I do not know how to get a more realistic speed: /

Thank you in advance!
