Optionaloptions:
BodyOptions
Protected_group
bounding box cache, without padding
Protectedcentered
is body centered
optimization for convex polygons
Readonlydestroy$
When Lifecycle Object is destroyed, it emits and closes this subject. Along with destroying his children, which in turn behave the same.
was the polygon modified and needs update in the next checkCollision
Parent GameObject is assigned at creation.
is it a convex polgyon as opposed to a hollow inside (concave) polygon
static bodies don't move but they collide
trigger bodies move but are like ghosts
Each Lifecycle Object has label for pixi debugging.
maximum x bound of body
maximum y bound of body
minimum x bound of body
minimum y bound of body
bodies are not reinserted during update if their bbox didnt move outside bbox + padding
Protectedpointsbackup of points used for scaling
Protected
Readonlyscalescale Vector of body
Optionalsystem
reference to collision system
Readonlytype
type of body
Readonlytypefaster than type
Readonlyupdate$
When Lifecycle Object is updated, it emits this subject. Along with updating his children, which in turn behave the same.
Optionaluserallows the user to set any misc data for client use
group for collision filtering
Values in BodyGroup are predefined and used each the body type and should not be used for custom filtering
0b00000001 << 16 to
0b01000000 << 16 (max 0x7fffffff) are
free to use for custom groups

is polygon centered?
flag to set is polygon centered
allow approx getting of scale
allow easier setting of scale
allow exact getting of scale x - use setScale(x, y) to set
allow exact getting of scale y - use setScale(x, y) to set
updating this.pos.x by this.x = x updates AABB
updating this.pos.y by this.y = y updates AABB
Called to destroy can cleanup Lifecycle Object.
Draws exact collider on canvas context
Draws Bounding Box on canvas context
get body bounding box, without padding
Protectedgetreturns body split into convex polygons, or empty array for convex bodies
Get edge line by index
if true, polygon is not an invalid, self-crossing polygon
