I'm happy to announce that rg3d 0.20 has been released. This release contains a lot of new features and improvements. The most large are WebAssembly support, initial 2D support and multi-layer terrains.

Let's start from the engine, there are 182 new commits compared to 0.19 and here's the most interesting changes:

rg3d

• WebAssembly support - check this online demo (opens new window)
• Initial 2D support - with lighting and physics (check it by cargo run --example 2d --release)
• Multi-layer terrains - now you can create outdoor scenes as you would in many other game engines - check example by cargo run --example terrain --release
• Added Framework which hides engine initialization and a game loop, all you need to do to start writing your game is to implement GameState trait for your game structure - here (opens new window) is the minimal example. Some examples have been refactored to use Framework, so can be used as a guide.
• Changed a way of setting shader uniforms - now it uses closure instead of set of enum variants which is a lot faster.
• Added Save mode for FileSelector and FileBrowser widgets - no need to type file name manually at the end of the path text box - there is separate "File name" field for that.
• Immediately load requested textures to GPU to prevent huge lag on first frame.
• Changed selection behaviour for TreeWidget.
• Refactored examples - now they should be more clear.
• Added continuous integration (huge thanks to Gideon Grinberg (opens new window) and Voodlaz (opens new window))
• Support for custom vertex formats.
• Ray-terrain intersection test.
• Ability to pause sound context.
• TextBox widget now can be in read-only state.
• Fixed procedural textures serialization.
• Added serialization support for arrays.
• Fixed instanced rendering.
• Fixed Screen-Space Ambient Occlusion banding issues.
• Fixed light scattering issues.
• Smart cascade selection for shadow maps.
• Added proc-macro for Visit trait (huge thanks to toyboot4e (opens new window))
• Fixed lighting issues.
• Added scroll options for ScrollViewerBuilder.
• Default shadows precision is now Full instead of Half which could cause graphical artifacts.
• Fixed critical physics serialization bug (opens new window).
• Added "on-demand" texture compression via tbc (opens new window) crate which supports R8RGTC, RG8RGTC, DXT1, DXT3, DXT5 compression.
• Improved renderer performance.
• Built-in profiler now able to print result in a string.
• Added parallax mapping.
• Improved performance of UI layout and message routing.
• Added tooltips and context menus (huge thanks to MinusGix (opens new window)).
• Ambient lighting belongs to scene, not renderer as it was before.
• Multiple expansion strategies for Tree widget.
• Fixed selection in ListView.
• Added first overview of engine's architecture - it should help newcomers to be able to easily start contributing.
• Minor fixes and improvements.

rusty-editor (opens new window)

rusty-editor has gain lots of improvements for last few months. One of the huge improvements is the terrain editor. Check this video:

There are 98 new commits compared to 0.7, here's the most interesting changes:

• Sound editor - now it is possible do add and edit sound sources.
• Added Grid snapping for Move interaction mode.
• Fixed Move interaction mode - now it correctly handles complex hierarchies and multi-selection.
• Improved Settings window - now it has separate categories instead of huge list.
• Added continuous integration (huge thanks to Voodlaz (opens new window))
• Added context menu for world outliner.
• Change main loop to prevent editor from spending too much time in logic update.

• Gizmos are full-bright and not affected by scene lights.
• Change selection to pasted nodes.
• Fixed uniform scaling.
• Fixed picking issues.
• Fixed "Fit Collider" issues.
• Now it is possible to change znear and zfar of preview camera.
• Level-of-detail (LOD) editor.

• Fixed potential infinite message loops that might hang editor.
• Added ability to clear command stack.
• Added ability to edit collision groups and masks for colliders
• Minor fixes and improvements.
