initialize code called once per entity var Trigger = pc.createScript('trigger') Triggers are only useful if something happens when they are triggered, so we need to add someĬode to fire and listen for events when the trigger is activated. Script component with some code attached. With this Entity we have a collision component but no rigidbody so it acts as a trigger. The next Entity we'll need is the trigger. This means that the surface is slightly rougher and slightly bouncier than the defaults. And we've also slightly increased the friction and We've increased theĮntity and the collision box properties so that it is nice and large. You can see in the attribute panel, that it has render, collision and rigidbody components. The first Entity we need in this tutorial is the green block that forms the ground.

Kinematic this Entity will not respond to forces, but will move if you directly set it's position or velocity.Dynamic this Entity will move under gravity and any other forces that you apply to it.The rigidbody component has a multitude of options which you can use to tune the propertiesįor details on each property take a look at the rigidbody documentation.įor this demo, the important property is the Type. To create a rigid body in your Scene, pick an Entity and add a rigidbody component and a collision component. With other rigid bodies and respond in a realistic manner. You can set it up with real physics properties like Mass and Friction it will collide Rigid Bodies Ī rigid body is a physical presence in your game world. You can see the trigger volume underneath the ramp displayed as a blue outline.

In this tutorial we're adding a largeīox-shaped Trigger Volume underneath the slope to catch the falling bodies and reset their position. To create a Trigger Volume all we need to do is add a collision component to an Entity. In particular, when using it with the rigidbody component, they must be Static. Note There are some limitations to the mesh collision,

Mesh Use any arbitrary mesh shape for the volume.

Useful for characters, as it can be tall and thin, but has a nice rounded-base with a single The most important property of a collision component is it's Type, this determines the shape of the volume that The collision component defines a shape which can be used either to trigger events if another Entity enters or exits it - we call thisĪ Trigger Volume - or it can be used together with the rigidbody component to give an Entity physical properties in your game - like This tutorial introduces the basics of rigid-body physics, collision detection and trigger volumes. Rigidbodies collide with each other, a sound is played on a collision and a trigger volume resets the shapes.
