A laser beam scene/node with advanced customization options. Most types of lasers can be made with it.

<aside> ☄️ This object is only available in the BLAST! version.

<aside> 💡 This page describes the laser beam, which is part of the BulletUpHell plugin. It is also available as a standalone addon but this addon has issues and is no longer maintained. The BLAST version works and integrates well with the rest of the plugin. This documentation page will assume you are using the BLAST version.

</aside>

If you're using the old standalone addon, install it by putting the LaserBeam Node folder into the addons folder and restart Godot.

If you want to use the bullet physic to make the laser move (overpowered for simple movements, use Tweens, Animations or simple code instead), spawn it using an Object Props or BulletNode Props (you must put the laser under a BulletNode ). You can use it to make highly customisable lasers.

Vocabulary:

• Casting : the action, for the laser, of determining its trajectory.

Signals :

• collided(position, collider, normal vector, full laser length, self-reference) : emitted when the laser collides with something.

Functions :

• reset_cast() : update the laser's beam. By default, the laser's update_cooldown is set to -1 (disabled) so you have to either change this value or call this function to update it manually.
• disable(reset, remove_nodes) : resets the laser beam and disables it. If remove_nodes, the Line2D and Raycast are removed.
• add_exception(node): nodes added as exceptions will not be collided with. This is to avoid colliding with a specific object even if the collision masks should allow the collision. For large lists of node, prefer using collision masks.
• remove_exception(node): remove a node in the exception list.
• clear_exceptions() : clear the exception list.

<aside> 💡 Lasers are Raycasts. All properties and functions of Godot Raycast2Ds can be used/called.
