Creating A Basic Speedometer - Tim_Ethen - 02.11.2010
My comments explain it pretty good. Please read this and do not just copy and paste it.
PHP Code:
#include <a_samp>
new Float:svx[MAX_PLAYERS]; // Holds Velocity X
new Float:svy[MAX_PLAYERS]; // Holds Velocity Y
new Float:svz[MAX_PLAYERS]; // Holds Velocity Z
new Float:s1[MAX_PLAYERS]; // This Is What Our Forumula Outputs
new s2[MAX_PLAYERS]; // This Is The Output When The Forumula's Ouput Is Round
new s3[MAX_PLAYERS][256]; // This Is The Text That Is Displayed To The User
new Text:sdisplay[MAX_PLAYERS]; // This Holds The Textdraw's ID
new stimer[MAX_PLAYERS]; // This Holds The Timer's ID (Used To Refresh Speed)
forward speedometer(playerid); // This Forwards The Timer To Our Function
public OnFilterScriptInit() { // This Is What Is Excuted When The FilterScript Starts
print(" ");
print(" ----------------------------------- ");
print(" ");
print(" Speedometer Filterscript Has Loaded ");
print(" ");
print(" ----------------------------------- ");
print(" ");
return 1;
}
public OnFilterScriptExit() { // This Is What Is Excuted When The FilterScript Ends
print(" ");
print(" ------------------------------------- ");
print(" ");
print(" Speedometer Filterscript Has Unloaded ");
print(" ");
print(" ------------------------------------- ");
print(" ");
return 1;
}
public OnPlayerConnect(playerid) {
sdisplay[playerid] = TextDrawCreate(10.0,200.0," "); // This Creates Our Textdraw And Stores The Id In The Varible In Front
TextDrawSetShadow(sdisplay[playerid],0); // This Removes Our Textdraw's Shadow ( Makes Easier To Read )
TextDrawSetOutline(sdisplay[playerid],1); // This Adds A Black Outline To Our Textdraw ( Makes Easier To Read )
TextDrawFont(sdisplay[playerid], 2); // This Changes Our Textdraw's Font ( I Think This Ones Makes It Easier To Read )
TextDrawShowForPlayer(playerid,sdisplay[playerid]); // This Shows The User The Textdraw
return 1;
}
public speedometer(playerid) {
GetVehicleVelocity(GetPlayerVehicleID(playerid), svx[playerid], svy[playerid], svz[playerid]); // This Saves Our Velocitys To Our Varibles
s1[playerid] = floatsqroot(((svx[playerid]*svx[playerid])+(svy[playerid]*svy[playerid]))+(svz[playerid]*svz[playerid]))*100; // This Is Our Forumula ( I Don't Know How It Works )
s2[playerid] = floatround(s1[playerid],floatround_round); // This Rounds Our Output To The Nearest Whole Number
format(s3[playerid],256,"%i MPH", s2[playerid]); // This Format Our Text Into What We See
TextDrawSetString(sdisplay[playerid], s3[playerid]); // This Changes The Value Of Our Textdraw To What We Formatted
return 1;
}
public OnPlayerStateChange(playerid, newstate, oldstate) { // This Is The Callback That Is Called When A Person Changes State ( ex States In_Vehicle, Dead, Passenger, Speculating... )
KillTimer(stimer[playerid]); // This Stops Our Timer For When You Get Out Of Your Vehicle Your Speed Doesn't Keep Going
TextDrawSetString(sdisplay[playerid], " "); // This Sets Our Textdraw To Blank And Freezes Because We Stop The Timer ^
if(newstate == 2) stimer[playerid] = SetTimerEx("speedometer", 255, true, "i", playerid); // This Starts The Timer When The Player Changes His/Her State To Being The Driver
else if(newstate == 3) stimer[playerid] = SetTimerEx("speedometer", 250, true, "i", playerid); // This Start The Timer When The Player Changes His/Her Start To Being The Passenger
return 1;
}

Nice tutorial very useful
Re: Creating A Basic Speedometer - Steven82 - 02.11.2010
It is nice, but i think it's very plain no offense
Re: Creating A Basic Speedometer - Tim_Ethen - 02.11.2010
That is why is said ' Basic Speedometer '
Re: Creating A Basic Speedometer - Steven82 - 02.11.2010
**Removed**
Re: Creating A Basic Speedometer - pmk1 - 03.11.2010
nice! but by the way there is already two speedo tutorials.... didn't you see them? :P
Re: Creating A Basic Speedometer - [L3th4l] - 04.11.2010
Nice and simple.
PS: next time use [ pawn] [ /pawn]
Re: Creating A Basic Speedometer - Dime - 04.11.2010
Yes
Very nice tutorial.
Re: Creating A Basic Speedometer - Fresh9884 - 06.11.2010
Nice, Good for begginers.
Re: Creating A Basic Speedometer - Hiddos - 06.11.2010
Good job, at every section you explain what that line of code does. Even though it's one bump of code in a single tag and the variables aren't fully optimized, this is brilliant. Good job!
Re: Creating A Basic Speedometer - [WSF]ThA_Devil - 08.11.2010

Re: Creating A Basic Speedometer - sim_sima - 13.06.2011
Next time, embed PAWN code in stead of PHP.

Nice tutorial though.
Re: Creating A Basic Speedometer - Jack_Rocker - 14.06.2011
I like this because it has been explained well, however there are already speedo tutorials! Try and make your tutorials a bit more unique! anyways.... 8/10
Re: Creating A Basic Speedometer - Namaco - 14.06.2011
Well knowing beginners they will copy and paste but indeed nice tutorial I wonder if it is a accurate one that shows the real speed not like going from 10 to 25
Re: Creating A Basic Speedometer - JamesMarcello - 04.07.2011
Well I'M super NEW to Scripting, Where exactly would i add this?
Re: Creating A Basic Speedometer - =WoR=Varth - 04.07.2011
Save it in your filterscript folder.
Don't forget to add it in your server.cfg
Re: Creating A Basic Speedometer - X3nZ - 11.07.2011
Well this isn't a tutorial because of the fact it doesn't explain nothing AT ALL.
