Warning

This is an extension made by a community member and it only got through a light review by the GDevelop extension team. As such, we can't guarantee it meets all the quality standards of fully reviewed extensions.

It handles basic collisions with 3D boxes but rotations around X and Y axes are not supported.

This extension is deprecated. The 3D physics engine should be used instead.

3D jump (deprecated)

Jump and fall along Z axis.

Behavior actions

Abort jump
Abort the current jump and stop the object vertically. This action doesn't have any effect when the character is not jumping.

See parameters

Parameter 0: 👾 Object
Parameter 1: 🧩 Behavior

Land on the floor
Stop the object from falling and land on the floor. The object will start falling again the next frame.

See parameters

Parameter 0: 👾 Object
Parameter 1: 🧩 Behavior

Separate from platforms
Separate from walls and land on platforms. 3D boxes rotated around X and Y axes are not supported.

See parameters

Parameter 0: 👾 Object
Parameter 1: 🧩 Behavior
Parameter 2 (👾 Object): Platform
Parameter 3 (🧩 Behavior): 3D capability

Allow jumping again
When this action is executed, the object is able to jump again, even if it is in the air: this can be useful to allow a double jump for example. This is not a permanent effect: you must call again this action everytime you want to allow the object to jump (apart if it's on the floor).

See parameters

Parameter 0: 👾 Object
Parameter 1: 🧩 Behavior

Current falling speed
Change the current falling speed of the object. Its value is always positive.
