Warning

This is an extension made by a community member — but not reviewed by the GDevelop extension team. As such, we can't guarantee it meets all the quality standards of official extensions.

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

3D jump

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.

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

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

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).

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

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

Gravity
Change the gravity of the object. Its value is always positive.

Jump height
Change the jump height of the object. Its value is always positive.

Jump sustain time
Change the jump sustain time of the object. Maximum time (in seconds) during which the jump strength is sustained if the jump key is held - allowing variable height jumps.

Maximum falling speed
Change the maximum falling speed of the object. Its value is always positive.

Stop falling when Z equals 0
Change if stop falling when Z equals 0.

Simulate jump key press
Simulate a press of the jump key.

Behavior conditions

Can jump
Check if the object can jump.

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

Current jump speed
Compare the current jump speed of the object. Its value is always positive.

Current vertical speed
Compare the current speed of the object on Z axis. Its value is negative when the object falls.

Gravity
Compare the gravity of the object. Its value is always positive.

Is falling
Check if the object is falling.\nNote that the object can be flagged as jumping and falling at the same time: at the end of a jump, the fall speed becomes higher than the jump speed.

Is jumping
Check if the object is jumping.

Is on floor
Check if the object is on a platform.

Jump height
Compare the jump height of the object. Its value is always positive.

Jump sustain time
Compare the jump sustain time of the object. Maximum time (in seconds) during which the jump strength is sustained if the jump key is held - allowing variable height jumps.

Maximum falling speed
Compare the maximum falling speed of the object. Its value is always positive.

Stop falling when Z equals 0
Check if stop falling when Z equals 0.

Behavior expressions

Expression Description
Object.Jump3D::CurrentFallSpeed() Return the current falling speed of the object. Its value is always positive.
Object.Jump3D::CurrentJumpSpeed() Return the current jump speed of the object. Its value is always positive.
Object.Jump3D::CurrentVerticalSpeed() Return the current speed of the object on Z axis. Its value is negative when the object falls.
Object.Jump3D::Gravity() Return the gravity of the object. Its value is always positive.
Object.Jump3D::JumpHeight() Return the jump height of the object. Its value is always positive.
Object.Jump3D::JumpSustainDurationMax() Return the jump sustain time of the object. Maximum time (in seconds) during which the jump strength is sustained if the jump key is held - allowing variable height jumps.
Object.Jump3D::MaxFallingSpeed() Return the maximum falling speed of the object. Its value is always positive.
