Description

Description:

Transforms position from camera coordinate space to world coordinate space. Camera axes are relative to camera orientation. x axis goes from left of the camera to right of the camera, z axis goes from underneath the camera to above the camera and y axis goes from back of the camera to where the camera is looking.

Groups:

Camera ControlPositions

Syntax

Syntax:

positionCameraToWorld cameraPos

Parameters:

cameraPos: PositionRelative - Relative camera position, format [x, z, y]

⚠

Note that y and z for this command are swapped around, which is different from your usual model space coordinates format

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] ] */

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];
