World Class
Look at the World reference pages before reading these docs.
https://p5play.org/learn/world.html
A world object is created automatically by p5play. There can only
be one world per p5.js instance.
This class extends planck.World and adds some p5play specific
features.

Methods
getSpriteAt
-
x -
y
Returns the sprite at the top most layer position where the mouse click occurs
Parameters:
-
xNumber -
yNumber
Returns:
a sprite
getSpritesAt
-
x -
y
Returns the sprites at a position.
Parameters:
-
xNumber -
yNumber
Returns:
an array of sprites
step
-
timeStep -
velocityIterations -
positionIterations
Performs a physics simulation step that advances all sprites' forward in time by 1/60th of a second if no timeStep is given.
This function is automatically called at the end of the p5.js draw loop, unless it was already called inside the draw loop.
Parameters:
-
timeStepNumber- time step in seconds
-
velocityIterationsNumber -
positionIterationsNumber
Properties
allowSleeping
Boolean
"Sleeping" sprites get temporarily ignored during physics simulation. A sprite starts "sleeping" when it stops moving and doesn't collide with anything that it wasn't already touching.
This is a performance optimization that can be disabled for every sprite in the world.
Default: true
gravity.x
Unknown
Gravity force that affects all dynamic physics colliders.
gravity.y
Unknown
Gravity force that affects all dynamic physics colliders.
offset.x
Unknown
offset.y
Unknown
velocityThreshold
Number
The lowest velocity an object can have before it is considered to be at rest.
Adjust the velocity threshold to allow for slow moving objects but don't have it be too low, or else objects will never sleep.
Default: 0.19
