1.5 Release: Physics engine, TypeScript support
This version 1.5 update focuses on the lack of features for action games large-scale project development, through the provision of physics engine, camera and TypeScript support.
Cocos Creator is now able to develop all kinds of action games and large projects for much better experience. In addition to the high expectations of the community requested new features, we once again optimized the engine load logic, a substantial increase in the scene loading and parse speed; In addition, we refactored the Windows desktop and Android platform Label and EditBox implementation, greatly enhanced the experience and compatibility.
- Integrated Box2D physics engine, add rigidbody and joint components
- Add Camera components to support high speed scrolls without loss of performance
- TypeScript and ES6 Class support, fully enhanced IDE code prompt
- Optimize the scene loading process, the scene load speed increased by 38%
- Cross-project assets export / import, assets dependencis will be automatically associated.
- Enhance the experience and compatibility of Label and EditBox in the Windows desktop platform and Android platform
- Improved hot update with continued download after connection broken.
Below we will list details of key new features.
Integrated Box2D physics engine
Cocos Creator in the 1.5 version has finally integrated the well-known physics engine Box2D, this easy-to-use powerful physics engine will bring a comprehensive physical detection and computing power to Cocos Creator to fully support your actions and physical games.
In addition to the common physics engine functionality, Cocos Creator's integrated physical system incorporates Rigidbody and Joint components, plus Collider components tailored specifically for the physics engine. You can achieve interesting interactive effect just by placing a variety of different physics components in your scene. With the newly added Camera components, the editor can build scroller game levels with rich content very easily!
In the development of action and adventure games, the change of viewport or screen scroll across scene is essential. In earlier versions developers can only move all nodes of scene to simulate the effect of perspective movement, but a large number of node displacement operations will affect performance, especially after integrate physics engine. Each time moving the collision body will lead to the regeneration and calculation of the physical world.
And in the 1.5 version Camera component can be added to solve the problem of moving perspective. Camera component can specify one or more nodes as the camera rendering target. You can drag the root node of the scene into the Camera target list, then just move the node with Camera component will give you the effect of viewport moving across the scene. Camera rendering is achieved through the matrix operation, so the scene will not bring in additional overhead
TypeScript and ES6 Class support
In order to better support coding in various IDEs (such as VS Code, WebStorm, etc.) with full code prompt and auto complete, we made a refactoring of the declaration of cc.Class in version 1.5 and can now use ES6 or TypeScript to declare components and write game logic in Cocos Creator.
Many users who have experience with strong typed language before using Creator give feedback about poor code prompts and automatic completion. This is mainly due to the editor needs the special declaration format for data serialization. But major IDEs cannot recognize the format for properly code parse and code prompt. In this version's refactoring we introduced the decorator syntax to help the editor to identify the data, and then we can use ES6 and TypeScript standard syntax to declare cc.Class and cc.Component. Use the standard syntax will make sure all mainstream IDE can parse the code correctly and can correctly prompt almost all the relevant interface code!
TypeScript supports strong typing declarations that provide more accurate interface communication specifications and error reporting for large projects that are collaboratively developed. Recommend the relevant strong type of language development experience and large-scale project technical team to try!
Scene loading speed increased by 38%
The biggest advantage of web game is instant play without installation, so web game scene loading speed, especially the initial scene loading speed is essential for user experience and retention. This update has included many optimization for scene asset loading, using the object pool to greatly reduce the frequency of object creation in the uuid-loader and deserialize modules, with a 38% increase in scene loading speed during local preview. But the actual project load speed bottleneck may come from the network connection speed, so the actual game speed increase depends on network settings, but basically there will be 200ms ~ 300ms improvement at least.
Cross-project asset import / export
In the previous release, we implemented the functionality of sharing a asset folder between projects by editor extension system, but there were more users who wanted us to provide a simpler, more direct, cross-project import and export mechanism, so that we can export assets from existing projects into new projects, or separate art and developer projects.
Through the main menu "File -> Import / Export Assets" to open the assets import and export tool. We can easily drag a scene or Prefab for export, the tool will automatically list the assets dependencies, then automatically generated zip package for all exported asset files. In another project you can easily import the zip package. If you encounter uuid conflict you can also choose to automatically update uuid to retain two versions of the assets.
- [Scripting] Add support for TypeScript script, add support for ES6 Class declaration for cc.Class and components. Enhanced code prompts in mainstream IDEs.
- [Editor] Add asset export/import tool with full dependencies.
- [Editor] Only one part of the large-size code file is previewed in the Properties panel to improve the editor performance when browsing large files
- [Editor] Add the option "Load in the editor" for the script assets when checked "Import as plugin". To determine a plugin script whether should be loaded in the editor, to improve the efficiency of the scene open.
- [Editor] Exports all CCClasss for all project scripts by default.
- [Editor] When the custom engine path fails to load, an error is reported and an attempt is made to use the built-in engine

You can fix it by generate a tiledmap map with extruded pixel around each tile (If you use the shoebox to generate a map, you need to set extrude to 1, padding is set to 2)
- [Engine] Optimized the deserialization and download of asset operations when the web platform loads scenes.
