The first post has it.

4) Does MPGetTrailerTowingVehicle loop through all vehicles to find the towing vehicle or do you keep track of trailers using OnPlayerUpdate and OnUnoccupiedVehicleUpdate?

Thanks

2. Surely, yes.

Seems to me, the higher the distance, the more off it would be.

4. Look at the source code for it

Re: [REL] Math Plugin - JernejL - 29.08.2011

when you use F variants of function (fast) you sacrifice some precision for speed.

Re: [REL] Math Plugin - SourceCode - 15.11.2011

Can you make a similar functions to detect vehicles too? native MPGetAimTarget(PlayerID, Float:SeekRadius = 50.0);

Re: [REL] Math Plugin - Niko_boy - 15.11.2011

superb , gonna try some codes
thank you for it 3))

Re: [REL] Math Plugin - leong124 - 17.11.2011

I've problem in FMPVecLength when I update this plugin, and recompiled my gamemode.
Here's crashdetect log:

Sorry if it is reported or has a solution already.

Edit:
I've checked the source code and I found that there's a typo in your MathPlugin.inc:

Re: [REL] Math Plugin - beckzy - 22.12.2011

Is this plugin still in beta/WIP state? and does it support 0.3d?

It supports 0.3d. I'm using it.

Re: [REL] Math Plugin - beckzy - 23.12.2011

Are there any known bugs with it?

Re: [REL] Math Plugin - leong124 - 24.12.2011

Probably no. However, it uses an old version of sampgdk if I am right.

Re: [REL] Math Plugin - TheArcher - 03.01.2012

I don't really understand this native

pawn Код:

native Float:MPDistanceCameraToLocation(Float:CamX, Float:CamY, Float:CamZ, Float:ObjX, Float:ObjY, Float:ObjZ, Float:FrX, Float:FrY, Float:FrZ); // calculates how distant target aim is from camera data pointed towards a certain point

can you do an example in a callback?

Re: [REL] Math Plugin - RyDeR` - 04.01.2012

Put camera position in Cam_, the position of the object (or point) in Obj_ and the camera front vector in Fr_.

Re: [REL] Math Plugin - DrTHE - 04.01.2012

Thanks, is creative ^^

Maybe i've read wrong. It says " calculate " not " putting camera on that position ", i'm going wrong. :S

Re: [REL] Math Plugin - zgintasz - 09.06.2012

Please, help me. I don't understand, why does it happens

. Please, fix it

stock function( playerid, vehicleid )

    new
        Float:offsetPos[ 3 ],
        Float:result[ 3 ]

    CreateObject( 324, result[ 0 ], result[ 1 ], result[ 2 ], 0.0, 0.0, 0.0 );
    return false;
}

Re: [REL] Math Plugin - cyber_punk - 04.10.2012

Any chance we can get the source with the sampgdk folders included? I wanted to add this to MPGetAimTarget Nero3d's GetPlayerCameraWeaponVector so that way the aim target will be accurate with weapons but I can not get the project to compile with MSVC. (Has to do with paths not being correct)

Re: [REL] Math Plugin - TheArcher - 01.02.2013

erm erm... where's the source code? :/

Re: [REL] Math Plugin - JernejL - 25.03.2015

Since ****** code is shutting down i've ported the project over to github.

I added a few natives that can deal with NaN and Inf floats.
