Collisions

Understanding how collisions work in your character is essential for movement glitches and physics behavior.

R6

An R6 character consists of 6 body parts:

Head, Torso, Left Leg, Right Leg, Left Arm, Right Arm

Each part follows specific collision rules:

Body Part	Default Collision	Can Be Modified
Head	Collidable	✅ Yes
Torso	Collidable	⚠️ Partial
Left Leg	Not Collidable	❌ No
Right Leg	Not Collidable	❌ No
Left Arm	Not Collidable	❌ No
Right Arm	Not Collidable	❌ No
HumanoidRootPart	Not Collidable	❌ No

---

R15

R15 characters have more segmented body parts, but fewer collision modifications are possible:

Body Part	Default Collision	Can Be Modified
Head	Not Collidable	❌ No
Upper Torso	Collidable	⚠️ Partial
Lower Torso	Collidable	⚠️ Partial
HumanoidRootPart	Collidable	❌ No
Left Foot	Not Collidable	❌ No
Right Foot	Not Collidable	❌ No
Left Hand	Not Collidable	❌ No
Right Hand	Not Collidable	❌ No
Left Lower Leg	Not Collidable	❌ No
Right Lower Leg	Not Collidable	❌ No
Left Upper Leg	Not Collidable	❌ No
Right Upper Leg	Not Collidable	❌ No
Left Lower Arm	Not Collidable	❌ No
Right Lower Arm	Not Collidable	❌ No
Left Upper Arm	Not Collidable	❌ No
Right Upper Arm	Not Collidable	❌ No

⚠️ Notes

• On R6, head collision can be completely disabled using certain glitches.

• On R6 and R15, torso collision behaves differently while jumping:

  • R6: Torso
  • R15: Upper + Lower Torso

• In both cases, torso collisions are disabled during the Jumping state.
