# FindRotation3D

This function takes two sets of XYZ coordinates. It returns the 3D direction from point A to point B. This can for example be used to make objects point at specified point

## Syntax

`float float float findRotation3D( float x1, float y1, float z1, float x2, float y2, float z2 )`

### Required Arguments

• x1: The X coordinate of the starting point.
• y1: The Y coordinate of the starting point.
• z1: The Z coordinate of the starting point.
• x2: The X coordinate of the target point.
• y2: The Y coordinate of the target point.
• z2: The Z coordinate of the target point.

## Code

```function findRotation3D( x1, y1, z1, x2, y2, z2 )
local rotx = math.atan2 ( z2 - z1, getDistanceBetweenPoints2D ( x2,y2, x1,y1 ) )
rotx = math.deg(rotx)
local rotz = -math.deg( math.atan2( x2 - x1, y2 - y1 ) )
rotz = rotz < 0 and rotz + 360 or rotz
return rotx, 0,rotz
end
```

## Example

This command makes the player's vehicle to rotate at vehicle near it. Note: This example needs OOP to be enabled in order to work

Client-side example
```local function setRotationAtNearestVehicle()

if not localPlayer.vehicle then return end

local nearestVehicle = false
local dist = 10000
for index,vehicle in ipairs(getElementsByType("vehicle",root,true)) do
if getDistanceBetweenPoints3D(localPlayer.vehicle.position,vehicle.position) < dist and localPlayer.vehicle ~= vehicle then
nearestVehicle = vehicle
dist = getDistanceBetweenPoints3D(localPlayer.vehicle.position,vehicle.position)
end
end

local x1,y1,z1 = getElementPosition(localPlayer.vehicle)
local x2,y2,z2 = getElementPosition(nearestVehicle)
local rx,ry,rz = findRotation3D(x1,y1,z1,x2,y2,z2)

localPlayer.vehicle.rotation = Vector3(rx,ry,rz)

end

```

Thanks for ccw for alternative getCameraRotation function which formula is used in this function. Also thanks for Doomed_Space_Marine for more accurate formula for z-axis which is used in findRotation
