.gravity

public this .gravity([comp])

comp

The name of a component that will stop this entity from falling

Enable gravity for this entity no matter whether comp parameter is not specified, If comp parameter is specified all entities with that component will stop this entity from falling. For a player entity in a platform game this would be a component that is added to all entities that the player should be able to walk on.

Example

Crafty.e("2D, DOM, Color, Gravity")
 .color("red")
 .attr({ w: 100, h: 100 })
 .gravity("platform")

.gravityConst

public this .gravityConst(g)

g

gravitational constant

Set the gravitational constant to g. The default is .2. The greater g, the faster the object falls.

Example

Crafty.e("2D, DOM, Color, Gravity")
  .color("red")
  .attr({ w: 100, h: 100 })
  .gravity("platform")
  .gravityConst(2)

.antigravity

public this .antigravity()

Disable gravity for this component. It can be reenabled by calling .gravity()
