3D Platformer Sample

Level 4

Overview

Moving platforms are a common feature in many modern games, but creating them can be deceptively tricky. This sample demonstrates how to create a moving platform system using the default 3D Kinematic Character Controller (KCC). It is a good starting point for implementing your own movement systems to drive more complex behaviour.

Highlights

FPAnimationCurve Usage

The use of FPAnimationCurve in the movement and rotation systems allows the user to specify the precise shape of the Platform's movement or rotation, including any sudden changes in direction or speed. Additionally, the use of pre-defined curves makes the code easier to read, as it eliminates the need for manual specification of the platform's movement at each point in time.

Inertia

This technical sample includes the option in the PlayerPlatformControllerAsset to transfer the platform's inertia to the player when they exit the platform. The platform's velocity is then applied to the player until they hit the ground or a new platform.

Description

1) Sample Scene

Select the scene dropdown menu in the editor window and click the "Game" scene. This scene provides a general example of what a platform layout would look like in game.

2) PlatformConfig

This technical sample utilizes the PlatformConfig asset in order to make moving platform behaviour easy to understand and manipulate.

Field Description
MovementAmplitude The amplitude of the movement related curves.
RotationAmplitude The amplitude of the rotation related curves.
MovementAxis Flags for which axis movement should be applied to.
XMovementCurve The movement curve for the X axis.
YMovementCurve The movement curve for the Y axis.
ZMovementCurve The movement curve for the Z axis.
RotationCurve The rotation curve to be applied (Y axis)

3) Platform Component

The Platform component identifies an entity as a valid platform and contains the necessary data to move it.

Field Description
Config The PlatformConfig asset to use for this platform instance.

4) PlatformControllerConfig

The PlatformControllerConfig asset is used to configure how the player interacts with the platforms.

Field Description
ApplyRotationInertia Whether or not to apply rotation inertia after exiting a platform.
PlatformAxisInertia Defines what axis should the inertia be applied on.

5) PlayerPlatformController Component

The PlayerPlatformController component defines an entity that can interact with Platform entities.

Field Description
Config The PlatformControllerConfig to use for this controller instance.

Integration
