Create a Crouching System
I will show you how to create a Crouching System in Unity. You can use this for sitting or stealth action in your game. The hardest part is to prevent a the player to stand up, when he is under an object. We will prevent this by a raycast up. Have fun!
Code:
protected bool isCrouching = false;
protected CapsuleCollider CapCollider;
private void Crouch()
{
var crouchbutton = CrouchButton.Pressed || Input.GetKey(KeyCode.C);
if (!isCrouching && crouchbutton)
{
//crouch
CapCollider.height = 0.5f;
CapCollider.center = new Vector3(CapCollider.center.x, 0.25f, CapCollider.center.z);
isCrouching = true;
Actions.Sitting(true);
}
Debug.DrawRay(transform.position, Vector3.up * 2f, Color.green);
if (isCrouching && !crouchbutton)
{
//try to stand up
var cantStandUp = Physics.Raycast(transform.position, Vector3.up, 2f);
if (!cantStandUp)
{
CapCollider.height = 1f;
CapCollider.center = new Vector3(CapCollider.center.x, 0.5f, CapCollider.center.z);
isCrouching = false;
Actions.Sitting(false);
}
}
}
