Sprinting Mechanism

To add a sprint feature, you can modify the existing movement script by introducing a sprint variable:
csharp
public float sprintSpeed 2f;
private bool isSprinting false;
void Update() {
// … previous code …
if (Input.GetKey(KeyCode.LeftShift)) {
isSprinting true;
} else {
isSprinting false;
}
Vector3 movement new Vector3(moveHorizontal (isSprinting ? sprintSpeed : speed), 0f, moveVertical (isSprinting ? sprintSpeed : speed));
transform.Translate(movement * Time.deltaTime);
}

This code checks for the Left Shift key press and enables sprinting when held down. The player moves faster during sprint mode.

Sliding Mechanism

Sliding can add an exciting element to your gameplay, especially in platformer-style games. Here’s a simple sliding mechanism:
csharp
private float slideSpeed 2f;
private bool isSliding false;
void Update() {
// … previous code …
if (Input.GetKey(KeyCode.LeftControl)) {
isSliding true;
} else {
isSliding false;

}
if (isSliding && transform.position.y < terrainHeight) {
Vector3 movement new Vector3(moveHorizontal, -slideSpeed * Time.deltaTime, moveVertical);
transform.Translate(movement);
}
}

This code checks for the Left Control key press and enables sliding when held down. The player slides downwards when on a terrain surface.

Wall Jumping Mechanism

Wall jumping is a popular mechanic in platformer games that allows players to jump off walls and gain extra height. Here’s a basic implementation:
csharp
private float wallJumpForce 7f;
private bool isWallSliding false;
private RaycastHit hitInfo;
void Update() {
// … previous code …
if (Physics.Raycast(transform.position, transform.right, out hitInfo, 0.1f)) {
if (!hitInfo.collider.isTrigger) {
isWallSliding true;
}
} else {
isWallSliding false;
}
if (Input.GetKeyDown(KeyCode.Space) && isWallSliding) {
GetComponent().AddForce(transform.right wallJumpForce + Vector3.up wallJumpForce, ForceMode.Impulse);
}
}

This code checks for a wall collision and enables wall sliding when in contact with a wall. When the Space key is pressed while wall sliding, the player performs a wall jump.

Summary

By mastering player movement in Unity 3D, you can create captivating, interactive experiences that keep players engaged for hours. From basic movement to advanced techniques like sprinting, sliding, and wall jumping, there’s always something new to learn and explore.
