Don't miss out on the latest and greatest new features in Construct 3

Notes

This week we've made a range of changes to make Construct handle 3D positions and sizes more naturally. Previously Construct was a purely 2D engine, and one of the very first features we added was the ability to move 2D objects up and down on the Z axis. At the time we named this feature 'Z elevation'. That made sense at the time, but now it's a bit of an odd way to treat 3D content. So we've changed Z elevation to just be the Z component of the position, and updated a range of features to treat the Z co-ordinate the same as the X and Y co-ordinates. Similarly the 'Z height' property of 3D shape is really the depth component of its size, and so we've also updated a range of associated features accordingly. These changes are quite far-reaching, affecting the UI, event sheets, and scripting/SDK, but for the most part these are backwards-compatible and so existing projects should continue working the same.

Other changes include an update for Windows WebView2, an optimization for 3D models, and a big batch of bug fixes, including several for the timelines feature. Happy testing!

  • It would be a really good time to introduce actual Vec2 and Vec3 data types now if there is a transition from 2D position to 3D position anyways.

    Needing 2 variables to store a position was already annoying enough.

    It will get even worse now every time you want to store or send a position. Add size to it and you have to create 6 variables where you only need 2 in other software.

    In Construct3 I have to do

    update_object(pos_x,pos_y,pos_z,size_x,size_y,size_z)

    instead of

    update_object(position, size)

  • Construct 3 adding more 3d has to be one of the best news in years

  • sweet updates

  • I noticed that the use of 'Z elevation' is still retained in 'Set mesh' action. Is this by design or has it been forgotten?

  • hi, does anyone know what file to use for importing 3D models? i have tried using stl and obj, but neither of these worked.

  • I am interested in both:

    1) Having more 3d Shapes like a cylinder

    2) Allowing current 3d shapes to be rotated on X/Y/Z axis I.E. Wedges can be inverted so the hypotenuse sits on the bottom instead of the top.

    Is this something you are working on or would consider implementing? It would save time for people having to make 3d objects in another program then import them for such a shape.

  • Curious, will zHeight (zScale) now be tweenable?

  • I want to rotate 3DShape objects around the z-axis (btw the 3D features are great)

  • Excellent update！
