ContactPoint

Properties

depth

depth: number = 0;

Defined in: src/physics/Contact.ts:9

---

id

id: number = 0;

Defined in: src/physics/Contact.ts:11

Which corners or faces made it: matched from step to step to carry the impulses over.

---

jn

jn: number = 0;

Defined in: src/physics/Contact.ts:13

Accumulated normal and friction impulses.

---

jt

jt: number = 0;

Defined in: src/physics/Contact.ts:14

---

lax

lax: number = 0;

Defined in: src/physics/Contact.ts:25

The point in each body's own frame when measured, so position correction can track its depth as they move and turn.

---

lay

lay: number = 0;

Defined in: src/physics/Contact.ts:26

---

lbx

lbx: number = 0;

Defined in: src/physics/Contact.ts:27

---

lby

lby: number = 0;

Defined in: src/physics/Contact.ts:28

---

massN

massN: number = 0;

Defined in: src/physics/Contact.ts:16

Per sub-step solver terms.

---

massT

massT: number = 0;

Defined in: src/physics/Contact.ts:17

---

rax

rax: number = 0;

Defined in: src/physics/Contact.ts:20

Offsets from each body's centre, refreshed every sub-step.

---

ray

ray: number = 0;

Defined in: src/physics/Contact.ts:21

---

rbx

rbx: number = 0;

Defined in: src/physics/Contact.ts:22

---

rby

rby: number = 0;

Defined in: src/physics/Contact.ts:23

---

target

target: number = 0;

Defined in: src/physics/Contact.ts:18

---

x

x: number = 0;

Defined in: src/physics/Contact.ts:7

World position when measured, and the depth there (px, < 0 a gap).

---

y

y: number = 0;

Defined in: src/physics/Contact.ts:8
