example if the developer wants to control pagination, in which case
he may know in advance the total number of lines the text will wrap to,
and then set it on batches.
Set the Style properties `boundsAlignH` and `boundsAlignV` or adjust them via the Text setters to change the alignment.
It works by calculating the final position based on the Text.canvas size, which is modified as the text is updated. Some fonts have additional padding around them which you can mitigate by tweaking the Text.padding property.
Setting a textBounds _doesn't_ update the wordWrapWidth, so be aware of the relationship between the two.
Call this method with nothing defined for any of the parameters to reset an existing textBounds.
#1824
Text.lineSpacing can now accept negative values without cutting the bottom of the Text object off. The value can never be less than the height of a single line of text.
Text.lineSpacing is no longer applied to the first line of Text, which prevents text from being cut off further down the Text object.
There are a bunch of signals added for Sprites; more when input is
enabled. However, very few of these signals are ever actually used. While
the previous performance update related to Signals addressed the size of
each Signal object, this update is to reduce the number of Signal objects
as used by the Events type.
As a comparison the "Particle: Random Sprite" demo creates 3200+ Signals;
with this change there less than 70 signals created when running the same
demo. (Each Event creates at 8 signals by default, and there is an Event
for each of the 400 particles.) While this is an idealized scenario, a
huge amount (of albeit small) object reduction should be expected.
It does this by creating a signal proxy property getter and a signal
dispatch proxy. When the event property (eg. `onEvent`) is accessed a new
Signal object is created (and cached in `_onEvent`) as required. This
ensures that no user code has to perform an existance-check on the event
property first: it just continues to use the signal property as normal.
When the Phaser game code needs to dispatch the event it uses
`event.onEvent$dispath(..)` instead of `event.onEvent.dispatch(..)`. This
special auto-generated method automatically takes care of checking for if
the Signal has been created and only dispatches the event if this is the
case. (If the game code used the `onEvent` property itself the event
deferal approach would be defeated.)
This approach is designed to require minimal changes, not negatively
affect performance, and reduce the number of Signal objects and
corresponding Signal/Event resource usage.
The only known user-code change is that code can add to signal (eg.
onInput) events even when input is not enabled - this will allow some
previously invalid code run without throwing an exception.
