Hi, I see you are using the unityscript tag, please note that this is (as explained in the tag info) a deprecated scripting language made by Unity, and not an encompassing term for all scripts in Unity. Your question is about C# (and I have removed the tag for you). Please only use this tag if you're working on legacy code using the actual language UnityScript. As we can see, there is a difference and its uses. If we want to create a game about destruction derby, basically cars ramming against each other for destruction, then we would use a default collider with “Is Trigger” unchecked and call OnCollisionEnter through scripting. The given other Collider has details about the trigger event, such as the name of its GameObject. Either of the two GameObjects must have a Rigidbody component. The Rigidbody component has both Rigidbody.useGravity and Rigidbody.isKinematic set to false. These prevents the GameObject from falling under gravity and having kinematic behavior.
When people using Unity to create the RPG game, trap is one of the biggest part during creating the game. I will talk about these function for helping people to create some basic element of RPG games.
Here is the example of using OnTriggerEnter, OnTriggerStay, and OnTriggerExit
Unity On Trigger Enter 2d
OnTriggerEnter
OnTriggerEnter is called when the Colliderother enters the trigger.
This message is sent to the trigger Collider and the Rigidbody (if any) that the trigger Collider belongs to, and to the Rigidbody (or the Collider if there is no Rigidbody) that touches the trigger. Notes: Trigger events are only sent if one of the Colliders also has a Rigidbody attached. Trigger events will be sent to disabled MonoBehaviours, to allow enabling Behaviours in response to collisions. OnTriggerEnter occurs on the FixedUpdate after a collision. The Colliders involved are not guaranteed to be at the point of initial contact.
Basically, when the target entering the area which the tag is called “Trap”, the target will take damage.
Here is the video example
The trigger box is on the trap and the trap tag is “Trap” so when the player entering, the system will check the tag to make sure is the trigger box tag is “Trap” or not.
OnTriggerStay
OnTriggerStay is called almost all the frames for every Colliderother that is touching the trigger.
This message is sent to the trigger and the collider that touches the trigger. Note that trigger events are only sent if one of the colliders also has a rigidbody attached. Trigger events will be sent to disabled MonoBehaviours, to allow enabling Behaviours in response to collisions.
It does the similar effect but when you stand on the trap you will lose you health continually.
OnTriigerExit
OnTriggerExit is called when the Colliderother has stopped touching the trigger.
Play Sound On Trigger Enter Unity
This message is sent to the trigger and the Collider that touches the trigger. Notes: Trigger events are only sent if one of the Colliders also has a Rigidbody attached. Trigger events will be sent to disabled MonoBehaviours, to allow enabling Behaviours in response to collisions. OnTriggerExit occurs on the FixedUpdate after the Colliders have stopped touching. The Colliders involved are not guaranteed to be at the point of initial separation.
The function only does the effect which when play leave and it will cost health. If you do not leave the trigger box, it will does nothing.
