Question to a simple thing :)

[Maurize]

Hey,

I´m creating a function that allows the player to get a car attached on his arms and able him to throw it.

ONLY PROBLEM:

I use setElementVelocity and now the car is only "flying" in one direction.

Is there a way to calculate the direction in which the car must fly?

Thanks,

Hope u understood me

Post the script.

CapY, there's no need to show the script.

Is there a way to calculate the direction in which the car must fly?

Be more specific! Do you want the car to fly exactly in front of itself?

[Maurize]

yep exactly. it should fly in the direction, the player got.

  
addEvent( "beiPower", true ) 
addEventHandler( "beiPower", getRootElement(), 
function() 
    local px, py, pz = getElementPosition( source ) 
    local rx, ry, rz = getElementRotation( source ) 
    local veh = createVehicle( 542, px, py, pz ) 
    attachElements( veh, source, 0, 0, 1.5, rx, ry, rz ) 
    bindKey( source, "mouse1", "down", 
function( player ) 
    local rx, ry, rz = getElementRotation( player ) 
    unbindKey( player, "mouse1", "down", source ) 
    setPedAnimation( player, "RYDER", "Van_Throw", 2000, false, false, false, false ) 
    detachElements( veh, player ) 
    setElementRotation( veh, 0, 0, pz ) 
    setElementVelocity( veh, 0, math.random( 1, 2 ), 0 ) 
    end ) 
end )

You can use

And basic math to do that.

benxamix2 this function is irritating me, could u give me more help about this?

  
addEvent( "beiPower", true ) 
addEventHandler( "beiPower", getRootElement(), 
function() 
    local px, py, pz = getElementPosition( source ) 
    local rx, ry, rz = getElementRotation( source ) 
    local veh = createVehicle( 542, px, py, pz ) 
    attachElements( veh, source, 0, 0, 1.5, rx, ry, rz ) 
    bindKey( source, "mouse1", "down", 
function( player ) 
    local px, py, pz = getElementPosition( player ) 
    local rx, ry, rz = getElementRotation( player ) 
    local nx, ny = getPointFromDistanceRotation( px, py, 1, rz ) 
    unbindKey( player, "mouse1", "down", source ) 
    setPedAnimation( player, "RYDER", "Van_Throw", 2000, false, false, false, false ) 
    detachElements( veh, player ) 
    setElementRotation( veh, 0, 0, pz ) 
    setElementVelocity( veh, nx, ny, 0 ) 
    end ) 
end ) 
-- "RIOT", "RIOT_ANGRY" -- 
  
function getPointFromDistanceRotation( x, y, dist, angle ) 
    local a = math.rad( 90 - angle ) 
    local dx = math.cos( a ) * dist 
    local dy = math.sin( a ) * dist 
    return x + dx, y + dy 
end 

[Maurize]

anyone? someone?

[12p]

Don't bump!!!

God, that's not very clever from you, Maurize! That will obviously don't work!

getPointFromDistanceRotation returns a 2D POSITION.

function getPointFromDistanceRotation( x, y, dist, angle ) 
    local a = math.rad( 90 - angle ) 
    local dx = math.cos( a ) * dist 
    local dy = math.sin( a ) * dist 
    return x + dx, y + dy 
end 
  
addEvent( "beiPower", true ) 
addEventHandler( "beiPower", getRootElement(), 
function() 
    local px, py, pz = getElementPosition( source ) 
    local rx, ry, rz = getElementRotation( source ) 
    local veh = createVehicle( 542, px, py, pz ) 
    attachElements( veh, source, 0, 0, 1.5, rx, ry, rz ) 
    bindKey( source, "mouse1", "down", 
function( player ) 
    local px, py, pz = getElementPosition( player ) 
    local rx, ry, rz = getElementRotation( player ) 
    local nx, ny = getPointFromDistanceRotation( px, py, 1, rz ) 
    unbindKey( player, "mouse1", "down", source ) 
    setPedAnimation( player, "RYDER", "Van_Throw", 2000, false, false, false, false ) 
    detachElements( veh, player ) 
    setElementRotation( veh, 0, 0, pz ) 
    setElementVelocity( veh, (nx - px)/10, (ny - py)/10, 0 ) --This determines the direction of the movement. You can increase or reduce the division "/10". 
    end ) 
end )

uh ur right, i saw this several minutes ago, but was unable tofix thanks
