Unreal Engine Blueprints Blueprint Physics and Collision 2

Question 1

Which Blueprint node applies a rotational force to a physics-enabled object?

Accepted Answer

Add Torque in Radians

Answer

Add Torque in Radians applies a continuous rotational force to a physics body, causing it to spin when called each tick.

Question 2

Which Blueprint node retrieves the current linear velocity of a physics-simulated Primitive Component?

Accepted Answer

Get Linear Velocity

Answer

Get Linear Velocity returns the current velocity vector of a physics body on a Primitive Component.

Question 3

What does the 'On Component Hit' event provide that 'On Component Begin Overlap' does not?

Accepted Answer

Hit result data including impact normal and impulse

Answer

On Component Hit fires during blocking collisions and provides a Hit Result struct with impact point, normal, impulse, and actor/component references.

Question 4

Which collision preset allows a projectile to detect overlapping actors without physically blocking them?

Accepted Answer

OverlapAll

Answer

OverlapAll sets all collision channels to Overlap, allowing the projectile to pass through objects while still triggering overlap events.

Question 5

What is the role of 'Linear Damping' in Unreal Engine physics?

Accepted Answer

Reduces an object's linear velocity over time to simulate drag

Answer

Linear Damping applies a drag-like force that gradually reduces linear velocity over time, simulating air resistance or friction.
