How do I create a 3D mechanic similar to the hole in Donut County?

Hi, everyone.

Is it possible to do something like the hole mechanic of Donut County using 3D in Construct?

Maybe I can make a similar effect using a isometric view in a 2D layout + physics behavior?

Thanks for your help!

3d objects have sprites assigned to a side.

changing the image of a 3d object, is as simple as changing the sprite it is set to look like.

you could have a 3d square inside the square, to have walls set as hollow appearance, with no top showing, then set this inner 3d cube to have the width of the desired hole size.

construct 3, unless im unaware, doesnt have great 3d rendering outside of isometric shapes

working it out, it will be sheerly aesthetics.

hope this is useful. more than likley someone else knows better.

there is always the option of just having hundreds of 3d squares... and deleting them.

thats going to slow the game down mind you

I guess one way could be to slice the ground plan in half by a horizontal line then use mesh distort to make the two halves of the hole. I can almost guarantee that the game did something simpler like using a stencil or just changing the depth function. But we are limited with what we can do 3d wise.

If you stick to isometric then just having a sprite fit the front of and back of the hole and zordering it with other objects should work.

Using 2d physics for 3d physics probably wouldn’t look great in most cases. Probably the idea could be to enable the object’s physics when their y is close to the hole’s y. Then for the hole you’d have two boxes on either side of the hole for its collision.

3d physics would look better and there’s probably a reasonable minimum physics engine needed.

cool tips! I will try to implement it and come back if I have any news or questions. thanks!!!
