Quintus is an easy-to-learn, fun-to-use HTML5 game engine for mobile, desktop and beyond!

The Quintus engine is an HTML5 game engine designed to be modular and lightweight, with a concise JavaScript-friendly syntax. In lieu of trying to shoehorn a standard OOP-game engine structure into an HTML5 JavaScript engine, Quintus takes some cues from jQuery and provides plugins, events and a selector syntax. Instead of a deep single-inheritance-only model, Quintus provides a flexible component model in addition to traditional inheritance to make it easier to reuse functionality and share it across games and objects.

Warning: Quintus is at a very early stage of development, use at your own risk.*

Quintus has no dependencies.

Check the build/ directory for single file builds.

• Update the Q.Scenes method to only render sprites that are visible in the grid. (so draw doesn't get called with thousands of sprites)
• Fix the collision methods to calculate a collision magnitude based on dot product of sprite velocities
• Added in A* Path finding
• Add in Babylon.js as a Optional Render mode(2D will not be removed)
• Add in Babylon UI as a optional UI alternative
• Add in common Ai algorithims(Feeling enemys,Agro enemys etc)
• Finish implementing basic LDK

• Added Global Json State loading
• Added Global Object pool
• Added Updates from last public forks of Quintus
• Added in cash.js,it's a JQUERY alternative that's 75% smaller than jquery but gets the job done
• Removed grunt build
• Added new simple build that works across the various ES versions of code
• Added in eruda adds a virtual debug window that can be viewed on mobile too
• Added in a Render mode that can be set to "pixel" or "hd" this optimizes the canvas using css for pixel games or None pixel art games
• Changed input so it can also trigger events based on arbitrary keys without needing a key schema
• Added a Optional debug stat that tells you how many of the game objects in the world are actually activley rendered/ticked
• Added a Generic and flexible timer
• Added Q.stime it's a simple utility function that just returns Human readable times into their milisecond,second,hourly etc time
• Added in alot more easining functions their were only 2 built in linear and Quadratic
• Added in variables MouseX and MouseY to make working with mouse positions less verbose
• Added in Q.Active this is another helper function that returns the current amount of objects that are deemed active
• Added, Particle Sprite types now automatically get tween component added to them on creation and automatically removed from the scene once no longer in use
• Added a Global Event emitter
• Added Q.Util this adds some common utility functions to speed up game development
• Added, platformer_tmx example,This example will continute to get updates as more features get added to quintus
• Added, Quintus.tmx object parser to detect and converting object array string properties to arrays(TMX does not support arrays)
• Added a BOX2D object type to the base sprite type,This automatically handles properly removing a newly inintialized physics object when it gets destroyed
• Added Default Key config overide Global Variable for desktop controls in the input module
• Added in spread syntax support for describing animation frames ie walk:"0..5" is the same as walk:[0,1,2,3,4,5]
• Added ,Animation frames now automatically assume atleast a 1/rate so you can just set the rate to 15 to say run this animation at 15 frames
• Added,2d module gravity can be overrided(By default its set to 1)
• Added,Box2D physics world settings can be overriden by utilizing Q.WorldPhysics
• Added,Q.Util now has a faster forEach,some,every,filter,map array functions(Benchmarks are linked in the quintus.js file/Q.Util section)
• Added setup.zindexit's 0 by defaut,you can lower it with this incase your games working with DOM elmements as the main UI
• Added a automatic refocus,When interacting with dom elements the users focus would get shifted
• Added setup[bootstrap,micron,animexyz,animatestyle] these libraries can be enabled by setting the library names to true,this does a remote file pull so that the core does not get overly bloated
• Added,Enabled Sorting by default for stages and sprite to sort by their z positions by defalt
• Fixed,The UI.HTMLElement it now correctly updates its position
• Added,Began partially parsing LDTK basic format export

• quintus_tmx.js TMX file extraction
• Multi-layer TMX Support + Sloped Tiles by lendrick
• TMX Object layer support
• TMX Repeater support
• TMX Sensor tile support

• Generate collision points performance optimization
• Disasteroids Example
• Initial Platformer Full Example
• Initial API Documentation
• Conditional Render and step support
• Tower Man Example

• Fix by A11oW to Quintus input
• #41 - repeated rounding issues
• Change SpriteSheet to use tileW, tileH instead of tilew, tileh

• Fix to sprite gridding
• Child sort and flip support
• Tile check fix from izidormatusov

• Added support for Web Audio output (iOS6 supported, Yay!)

• Added audio example in examples/audio

• Moved non-working SVG, DOM and Physics modules to extra/

• Added support for functions as direction options to follow (suggested by @gvhuyssteen )

  For Example:

    stage.follow(player, {

       x: true, 
  
       // Only follow y if the player has landed
       y: function(sprite) { return sprite.p.landed > 0 } 
    });
  

• Improved tween animations, by @fqborges fixes tween chaining and adds in an example in examples/tween/

Changes to your code:

• If you were using sound sprites, they have been removed.

• Fix to Q.UI.Button with an Asset
• Fix to MouseControls on Android
• Added UI example

• Added Q.GameState for storing global game state ..

• Add touch example with drag and locate details
• Added drawableTile and collidableTile to Q.TileLayer

Changes to your code:

• Your sprite's step method should no longer call this._super(dt) (in fact, sprites don't define a default super method anymore, so it'll cause a bug)- events are now handled by the Sprite.update(dt) method
