# Detecting collisions⤶
⤶
To detect when an object enters or exits a trigger, both GameObjects must have a collider component attached, with the `Is Trigger` box checked on the trigger GameObject.⤶
⤶
Then create a component on the `same GameObject` as the collider marked as a trigger, and inherit from `Component, Component.ITriggerListener`⤶
⤶
```c#⤶
⤶
public sealed class TriggerDebug : Component, Component.ITriggerListener⤶
{⤶
[Property] public NameTagPanel NameTag { get; set; }⤶
⤶
int iTouching;⤶
⤶
void ITriggerListener.OnTriggerEnter( Collider other ) ⤶
{⤶
iTouching++;⤶
⤶
NameTag.Name = $"{iTouching} touching\n{other.GameObject.Name} entered";⤶
}⤶
⤶
void ITriggerListener.OnTriggerExit( Collider other ) ⤶
{⤶
iTouching--;⤶
⤶
NameTag.Name = $"{iTouching} touching\n{other.GameObject.Name} left";⤶
}⤶
⤶
}⤶
```⤶
⤶
<note>NameTagPanel is a custom razor component that displays text on a **World Panel**</note>⤶
