We have separated the logic and render updates to permit slow motion and time slicing effects. We've fixed time calling to fix physics problems caused by variable time updates (i.e. collisions sometimes missing, objects tunneling, etc)
Once per frame calling for rendering and tweening to keep things as smooth as possible
Calculates a `suggestedFps` value (in multiples of 5 fps) based on a 2 second average of actual elapsed time values in the `Time.update` method. This is recalculated every 2 seconds so it could be used on a level-by-level basis if a game varies dramatically. I.e. if the fps rate consistently drops, you can adjust your game effects accordingly.
Game loop now tries to "catch up" frames if it is falling behind by iterating the logic update. This will help if the logic is occasionally causing things to run too slow, or if the renderer occasionally pushes the combined frame time over the FPS time. It's not a band-aid for a game that floods a low powered device however, so you still need to code accordingly. But it should help capture issues such as gc spikes or temporarily overloaded CPUs.
It now detects 'spiralling' which happens if a lot of frames are pushed out in succession meaning the CPU can never "catch up". It skips frames instead of trying to catch them up in this case. Note: the time value passed to the logic update functions is always constant regardless of these shenanigans.
Signals to the game program if there is a problem which might be fixed by lowering the desiredFps
Time.desiredFps is the new desired frame rate for your game.
Time.suggestedFps is the suggested frame rate for the game based on system load.
Time.slowMotion allows you to push the game into a slow motion mode. The default value is 1.0. 2.0 would be half speed, and so on.
Time.timeCap is no longer used and now deprecated. All timing is now handled by the fixed time-step code we've introduced.
- Sizing events:
- CHANGE: The `onResize` callback is called only from `preUpdate` (which
may be triggered from a window resize) and it will be called on
refreshes even if the parent size has not actually changed.
- A new `onSizeChange` Signal has been added. It is called _only_ when
the Game size or Game canvas size has changed and is generally more
applicable for performing layout updates.
- Game documentation now links to ScaleManager#setGameSize (which was
renamed from #setGameDimensions)
- Removed extra/legacy full-screen restore code
- Margins:
- Added `noMargins` flag; if set to true the Canvas margins will never
be altered. This also means that
- Margins are now set/cleared individually to avoid conflict with
'margins' style compound property
- Code consistency updates
- NOTE: Changing `game.width/game.height` via user code was always
problematic. This commit updates the documentation for such members as
read-only. The only supported way to change the GAME SIZE after it is
created is to use `ScaleManager#setGameDimensions`, which has been
added.
- The GAME SIZE will be reset to the initial (or as set by
`setGameDimensions`) values upon changing the scale mode or
entering/leaving full screen. This may be a breaking from 2.1.2 (but
many mode changes acted oddly prior).
- SHOW_ALL will now EXPAND it's parent container if it can. As per
@tjkopena 's notes, this should more closely represented the expected
behavior.
- SHOW_ALL will first try to expand by the OVERFLOW AXIS and then
attempt to resize to fit into the possibly larger area; use the
parent's max-height/max-width properties to limit how far SHOW_ALL can
expand.
- RE-BREAKING: This changes the behavior from 2.1.4 and makes it more like
2.1.3, with fixes.
- As per previous commit the ScaleManager _owns_ the margins and size of
the GAME CANVAS. To control the dimensions of the GAME CANVAS, use the min/max
height/width of the parent. Setting padding on the parent is _NOT_
supported.
- Fixes various issues with switching between Scale Modes
The width and height given to the Phaser.Game constructor can now be numbers or strings in which case the value is treated as a percentage. For example a value of "100%" for the width and height will tell Phaser to size the game to match the parent container dimensions exactly (or the browser window if no parent is given). Equally a size of "50%" would tell it to be half the size of the parent. The values are retained even through resize events, allowing it to maintain a percentage size based on the parent even as it updates.
Stage.offset has been moved to ScaleManager.offset
Stage.bounds has been removed, you can access it via Stage.getBounds.
Stage.checkOffsetInterval has been moved to ScaleManager.trackParentInterval
ScaleManager.hasResized signal has been removed. Use ScaleManager.setResizeCallback instead.
StateManager.clearCurrentState now handles the process of clearing down the current state and is now called if the Game is destroyed.
Game.destroy now clears the current state, activating its shutdown callback if it had one. It also now destroys the SoundManager, stopping any currently running sounds (#1092)
Input.Gamepad.destroy now destroys all connected SinglePads and clears event listeners.
SinglePad.destroy now clears all associated GamepadButton objects and signals.
A slightly obnoxious but necessary hack to prevent a race condition between the loading of Apache Cordova and Phaser itself.
Without waiting for the 'deviceready' event, Phaser can often load first, preventing any console messages from appearing to the user. Because Cordova writes to the platform's console (via CordovaLog), it must first be loaded and signal its own 'deviceready' event before console or plugin usage can occur. Otherwise, all messages and functionality is ignored.
If pause is called manually, codePaused should be set regardless of whether the game is currently paused or not. This would fix issues where a developer might not want the game to automatically resume when the screen regains focus.
Game checks if window.console exists before using it (should fix IE9 issues when dev tools are closed), however it is still used deeper in Pixi.
Body.loadData flagged as deprecated.
All the Debug methods have had the word 'render' removed from the start. So where you did `debug.renderSpriteInfo` before, it's now just `debug.spriteInfo`.
Debug methods that rendered geometry (Rectangle, Circle, Line, Point) have been merged into the single method: `Debug.geom`.
If your game references the old Phaser.StageScaleMode consts like SHOW_ALL you need to update them to Phaser.ScaleManager, i.e. Phaser.ScaleManager.SHOW_ALL.
All of the Project Templates have been updated to reflect the above change.
Sprite.smoothed and Image.smoothed allows you to set per-Sprite smoothing, perfect if you just want to keep a few sprites smoothed (or not).
Fixes#381.
Loader.setPreloadSprite() will now set sprite.visible = true once the crop has been applied. Should help avoid issues (#430) on super-slow connections.
Stage.aspectRatio has been moved to StageScaleMode.sourceAspectRatio (so now game.scale.sourceAspectRatio)
Stage.scaleMode has been moved to StageScaleMode.scaleMode (so now game.scale.scaleMode)
Stage.fullScreenScaleMode has been moved to StageScaleMode.fullScreenScaleMode (so now game.scale.fullScreenScaleMode)
Stage.canvas has been removed. It was only ever an alias for Game.canvas anyway, so access it via that instead.
Debug.renderPhysicsBody(body, color) is extremely useful for debugging the new physics bodies. Will draw the outline + points in the color given.
Debug.renderBodyInfo(sprite, x, y, color) will display lots of Sprite body data.
Canvas.getOffset now runs a strict/quirks check and uses document.documentElement when calculating scrollTop and scrollLeft to avoid Chrome console warnings.
The Time class now has three new methods: addEvent, repeatEvent and loopEvent. See the new Timer examples to show how to use them.
This allows moving the state.update() call to before world.update(),
meaning results of collisions checked in the state are available to
objects in their own update().
Throw exceptions if wrong format given to tilemap or textureatlas. Previously, old onload remained active and error happened in the wrong (and hard to diagnose) place.
