Event AnyDamage	Called when general damage is to be dealt. For informational purposes.
Event PointDamage	Meant to represent damage dealt by projectiles, hit scan or melee weaponry.
Event RadialDamage	Called when parent Actor receives Radial Damage (Ex: Explosion damage or indirect damage).
Event ActorBeginCursorOver	Called when using the mouse interface and cursor is moved over an Actor.
Event ActorEndCursorOver	Called when using the mouse interface and cursor is moved off an Actor.

UE5 Chaos Car Physics Issues and Solutions

Common Issues

Issue	Description
Vehicle resetting to player start	Vehicles will reset to the player start once passing a certain threshold in large partitioned worlds.
Steering Problems	Vehicles may have trouble steering correctly, causing understeer or oversteer.
Suspension Settings	Inconsistent suspension performance, leading to unrealistic handling.
Wheel Spinning	Wheels may spin uncontrollably, leading to a lack of traction.

Solutions

Issue	Solution
Vehicle Bouncing	Adjust the Chaos Physics sub-stepping settings. Increasing the number of sub-steps can help stabilize vehicle behavior on rough terrain.
Steering Problems	Tweak the steering curve in the vehicle's blueprint to provide a smoother response, and adjust the center of mass to a lower position to improve stability.
Suspension Settings	Experiment with different spring stiffness and damping values for the suspension to achieve a realistic and stable ride.
Wheel Spinning	Reduce engine torque and adjust the wheel friction curve to ensure better traction control.
