Physics Blocks

Why Physics Blocks Matter

The Physics families let graphs respond to simulation events and directly change body state.

These blocks are most useful when the preview scene has Physics V2 enabled and physics bodies are already attached to relevant meshes.

Physics Events

PhysicsCollisionEvent

Use PhysicsCollisionEvent when graph logic should react to collisions.

This block can expose collision-related data such as the other body, contact information, impulse, and penetration details.

Physics Actions

ApplyForce

Use ApplyForce for sustained force-like effects, especially when driven repeatedly over time.

ApplyImpulse

Use ApplyImpulse for instant velocity changes.

SetLinearVelocity

Use SetLinearVelocity when you want direct control over movement speed and direction.

SetAngularVelocity

Use SetAngularVelocity when you want direct rotational motion control.

SetPhysicsMotionType

Use SetPhysicsMotionType when the body's motion mode itself should change.

Physics Data

GetLinearVelocity

Reads the current linear velocity.

GetAngularVelocity

Reads the current angular velocity.

GetPhysicsMassProperties

Reads mass, center of mass, and inertia information.

Practical Notes

• Physics blocks depend on a physics-enabled scene.
• They are best tested against a preview scene that already contains physics bodies.
• When debugging these graphs, combine runtime stepping with visible scene motion so you can distinguish graph issues from simulation issues.
