Gets or sets the threshold buffer value for hit testing.

Syntax

JavaScript

get_hitTestBuffer();
set_hitTestBuffer(value);
Object.defineProperty('hitTestBuffer');

Property Value

Type	Description
double	The threshold buffer value for hit testing, in pixels. The default value is 37.5. Must be a value greater than or equal to 0.

Remarks

This property is used by the HitTestPoint and HitTestRect methods.

The value of HitTestBuffer can be used to make the test point "bigger" to compensate for errors and provide smoother hit-testing. For example, if buffer is 2, a square with a length of 4 units around test point will be used to perform the hit-testing.
