Physics

Kinemium contains Jolt and Box2D integrations plus UnifiedPhysicsService, which is the facade used by current world APIs.

Apply an impulse

local Workspace = game:GetService("Workspace")

local part = Instance.new("Part")
part.Anchored = false
part.Parent = Workspace

part:ApplyImpulse(Vector3.new(0, 20, 0))

Part:ApplyImpulse() delegates to UnifiedPhysicsService.

Raycast

local hit = Workspace:Raycast(
    Vector3.new(0, 20, 0),
    Vector3.new(0, -100, 0)
)

if hit then
    print("Hit:", hit)
end

Workspace:Raycast() delegates to UnifiedPhysicsService.Raycast.

Backends

• JoltPhysicsService: 3D Jolt integration.
• Box2DService: 2D Box2D integration.
• UnifiedPhysicsService: gameplay-facing facade shared by engine objects.

For new gameplay API, prefer the unified service where possible.
