# Damage Source

This component does the specified Damage to all *IDamageable* that qualifies for its condition. These are based on the mode and the duration of the damage source. 

**Modes:**

* **Volume:** Does damage amount as long as the damageable is within the volume. Needs a Collider set to Trigger.

* **Contact:** Needs a Collider (leave *isTrigger* unchecked). Important: don't forget to set your collision Layers accordingly.

* **Particle:** Needs a Particle Handler and a Particle System with Collisions turned on. The component deals the specified damage when the target is colliding with the particles.
* Tick Cooldown: specifies the time between two damage events. This is useful for dense particle systems where you don't want the player to suffer damage from each particle he collides with.

Important: Particle Mode only works with Continuous duration.

* **Ray:** Needs a [Ray Handler](https://app.gitbook.com/@runemarkstudio/s/deadly-dungeons/~/drafts/-MVv5Wz9S1GutR_VLVPo/traps/effect-handlers/ray-handler). This component deals damage when the Raycast from the handler hits its target, specified by Layer Mask. Can be used with all duration modes.

**Duration:**

* **Once:** the damage event is happening once per event.
* **Continuous:** the damage is dealt until the collision is happening (for example, the player is within the damage volume, or in contact with the trap's collider.)
* **Tick Cooldown** is the time (in seconds) between two damage events. 
* **Controlled by Mechanism:** the trap will only deal damage on certain Mechanism Events. Drag this component to an empty Event slot and specify an Action.
