Understanding Vehicle Collisions and Ragdoll Reactions

Physical Collision Properties

Vehicles and props in DynamX do not rely on standard block hitboxes. Instead, every object uses customized collision properties and weight values calculated in real time by the Bullet Physics Engine.

When testing vehicles on stunt tracks or driving near obstacles, collisions react dynamically:

• Low-speed contact against solid walls or guardrails will halt or redirect vehicle momentum.
• High-speed collisions interact with obstacle boundaries, producing sudden stops and momentum transfers across the vehicle chassis.
• Loose props hit by a moving car will shift or move according to their assigned weight and physical properties.

Observing Ragdoll Physics

Content packs can also introduce ragdoll models with full physical reactions during vehicle impacts:

1. Position ragdoll models along a test track or near road obstacles.

2. Drive a vehicle into the testing area to simulate an impact.

3. Upon impact, the ragdoll model reacts with full physics calculations, moving and tumbling dynamically according to the vehicle's speed and angle of contact.

This system allows players to run realistic crash tests and stunt driving demonstrations across their custom maps.
