VKC Node Collider

VKC Node Collider is a component to set what kind of collision detection a collider has on Vket Cloud.

Label	Function
Collider type	Specifies the type of collider.
Collider target	Specifies the target.
physics	Enables physics engine for the Box Collider.
Fixed	Fix the position of the Box Collider.
Enable body	You can choose whether to enable physics when the object is loaded.
Mass	Adjust the weight parameter.
Restitution	Adjust the coefficient of restitution.
Allow Cross Over	Specifies whether to allow penetration for the collider.
Cross Over Rate	The ratio of how much penetration is allowed. The closer to 0.0, the larger the range of penetration.
Extrusion Speed	Set the extrusion speed when the penetration ratio exceeds the allowable penetration ratio.
Grounding Detection	Set the grounding process. Grounding detection is the process of determining whether the top of the collider is on the ground and the process of riding on it if it is on the ground.

About Extrusion

The function of VKC Node Collider added in SDK13.0 that allows you to adjust the behavior of the extrusion process of collision detection. For example, you can allow a certain amount of penetration through a gap (collider) that cannot be passed through in the collision detection, or prevent small objects from interfering with movement.

Collider type

Type	Function
Collider	Plays the role of a collider.
Clickable	Allows players to click.
Area	A collider that can be passed through. By combining with VKC Item Area Collider, you can set any action when the player get inside the area.
Occlusion	Enable occlusion on contact. For instructions, please refer to Occlusion Culling.
Reflection Probe	Enable reflection probes on touch.
in View	Handled when you want to judge whether or not the object entered the field of view

Note

If collider type is set to other than Collider (i.e. Clickable, Area, Occlusion, Reflection Probe, inView), the player will not collide with the collider.

Collider target

Target	Function
All	Does not restrict the collision detection.
Avatar Only	Collision detection is enabled only for avatars.
Self Player Only	Collision detection is enabled only for the player themselves.

Note

The collider target setting is only effective when the collider type is Collider.

Grounding Detection

Label	Function
Auto	Automatically detects based on the collider size. Small sizes are disabled, and medium and large sizes are enabled.
Enable	Grounding detection enabled
Disable	Grounding detection disabled

About collision / area range detection by collider

The collision / area range detection by collider will be done by obtaining the player's lower body position as the orange circle shown below.
Collision visualization can be toggled by enabling the debug mode on VketCloudSettings / BasicSettings and pressing F3.
