F367 step 5 v2 — pulse-triggered instantaneous impulse on a body. Same shape as `physicsApplyForce` but applies an instantaneous velocity delta (Δv = impulse/mass) instead of a continuous force across one step. Use for explosions, kicks, projectiles — anything that should change a body's velocity discontinuously.

Parameters
| Parameter | Type | Default | Description |
|---|---|---|---|
paramImpulseX | float | 0 | Used when the `impulse` input port is unwired. Author-convenience static vector — same pattern as `physicsWorld.paramGravity{X,Y}`. step 10 |
paramImpulseY | float | 0 | Default Impulse Y (px/s · kg) step 10 |
paramPointX | float | 0 | Off-centre application point; (0, 0) = body centre. step 5 |
paramPointY | float | 0 | Default Point Y (body-local px) step 5 |
Use cases
- Ragdoll on hit — state-machine transition fires `physicsApplyImpulse.trigger`; impulse vector aimed away from the hit point. The character rags down naturally.
- Click-to-launch — `clickStateDispatcher.pulse` → `trigger`; impulse upward. Single click yields a one-shot launch.
- Collision-driven scatter — `physicsCollisionPulse.pulse` (v2 collision events) → `trigger`; impulse derived from the contact normal.
