Description

Description:
PositionCameraToWorld.jpg
Get the world coordinate space (AGL) from a camera-relative position.
Groups:
Camera ControlPositions

Syntax

Syntax:
positionCameraToWorld cameraPos
Parameters:
cameraPos: PositionRelative - relative camera position, format [x, z, y] (X = left-right, Z = below-above, Y = back-front)
⚠
This command has Y and Z axes swapped around, which is different from the usual model space coordinates format ([x, y, z]).
Return Value:
Array - camera world position, format PositionAGL

Examples

Example 1:
_worldPos = positionCameraToWorld _cameraPos;
Example 2:
Example demonstrating reversed Y and Z:
player setDir 0; // assuming player is looking forward hint str [positionCameraToWorld [0,0,0], positionCameraToWorld [0,0,1]]; /* [ [2481.35, 5671.21, 1.51395], [2481.35, 5672.21, 1.46955] ] */
Example 3:
_cameraAGLPosition = positionCameraToWorld [0,0,0];

By measuring the distance between the camera and the player one can determine whether 1st-person or 3rd-person view is being used:
if ((positionCameraToWorld [0,0,0] distance player)>2) then { hint "3rd person" } else { hint "1st person" };

The camera coordinate system is different from the model coordinate system: when modelToWorld uses [x, y, z] then positionCameraToWorld uses [x, z, y]. So for a steady camera the following is true:
positionCameraToWorld [5,10,15] == _camera modelToWorld [5,15,10];
