Class: Bounds

PIXI.Bounds

'Builder' pattern for bounds rectangles.

This could be called an Axis-Aligned Bounding Box. It is not an actual shape. It is a mutable thing; no 'EMPTY' or those kind of problems.

Members

maxX number

Default Value:
  • 0

maxY number

Default Value:
  • 0

minX number

Default Value:
  • 0

minY number

Default Value:
  • 0

updateID number

It is updated to _boundsID of corresponding object to keep bounds in sync with content. Updated from outside, thus public modifier.

Default Value:
  • -1
