Collider component reference

Click Add Component button at the bottom of Properties panel and then select Collider component from Collider Component, then you add the Collider component to the node.

Collider component properties

property	Function Explanation
Tag	The collider tag. If there are several collider components in a node, you can use the tag to judge which collider component on the node is collided.
Editing	Whether to edit this collider component, only used in the editor.

Detailed Explanation

One node can have several collider components, and these collider components can be different type.

We have three collider component types now, they are Polygon, Circle, Box. These components all inherit from Collider component, so the properties of the Collider component are also enjoyed.

Polygon collider component properties

property	Function Explanation
Regenerate Points	The vertices of the corresponding outline are automatically generated based on the texture pixels of the Sprite component on the node where the component is located.
Threshold	Indicates the minimum distance between the vertices of the generated texture outline. The larger the value, the fewer points are generated, which can be adjusted according to the requirements.
Offset	Position offset from Component to Node.
Points	Component vertices array

Circle collider component properties

property	Function Explanation
Offset	Position offset from Component to Node.
Radius	Component radius.

Box collider component properties

property	Function Explanation
Offset	Position offset from Component to Node.
Size	Component size.
