Construct 3 r472

Notes

In this release we've continued to do a lot of under-the-hood work to better prepare the Construct engine for 3D features. A key part of the engine is tracking bounding boxes of objects. Previously these bounding boxes were 2D, but now the engine tracks 3D bounding boxes so it has a built-in understanding of the extent of objects in 3D space. The 3D bounding box is available via expressions and a new script API (using a new AABB3D class, standing for Axis Aligned Bounding Box 3D). This work also allows for setting object's origin on the Z axis, which has allowed us to provide an option to set the Origin Z for 3D shape, as well as allowing negative heights (essentially mirror/flip but on the Z axis) for extra flexibility.

Work on the new 3D model plugin has also continued, with the new ability to choose multiple meshes to draw, a series of bug fixes, and a new icon to distinguish it from 3D shape.

Another key update in this release is to introduce a new workaround for gamepad input in Windows WebView2 exports. Currently an outstanding WebView2 bug stops gamepad input working. This can be worked around for non-Steam exports. However for Steam exports we now use a wrapper extension to access GameInput, a modern Windows API for accessing gamepads that supersedes prior APIs like XInput, DirectInput, and HID. Currently this only supports a single gamepad and may require installing the GameInput redistributable, but it should at least provide a way to use basic gamepad input for Steam games until the WebView2 bug is resolved.

Other changes include a new option to bound to viewport with the Bound to behavior (which has been renamed from Bound to layout), a new distance3d system expression, and support for three-value tweens to allow tweening X, Y and Z all at once. Happy testing!
