Description

Get camera direction

Syntax

camera.getDirection();

Return value

  • Vector3

Example

This function returns undefined or a valid result, if you point with your camera on something.

Client-Side
function pointingAt(distance) {
    const camera = mp.cameras.new("gameplay"); // gets the current gameplay camera

    let position = camera.getCoord(); // grab the position of the gameplay camera as Vector3

    let direction = camera.getDirection(); // get the forwarding vector of the direction you aim with the gameplay camera as Vector3

    let farAway = new mp.Vector3((direction.x * distance) + (position.x), (direction.y * distance) + (position.y), (direction.z * distance) + (position.z)); // calculate a random point, drawn on a invisible line between camera position and direction (* distance)

    let result = mp.raycasting.testPointToPoint(position, farAway, [1, 16]); // now test point to point

    return result; // and return the result ( undefined, if no hit )
}
