Little Big Tips > General tips > simple damage shake

Feel free to try this behaviour on the playable demonstration / prototype: Combat Wings.
_{Note: The purpose of this demonstration is to evaluate this gameplay mechanic. The scenario and the props are free assets from the Asset Store.}

Problem description

When the player airplane is hit, the big impact needs to shake it all!

Solution suggestion

Actually, in this case, the Camera is shaked when something hits the Player.
_{Note: The scope of this Little Big Tip is only the shakking. How to trigger the shaking after the Player is hit, it's up to you.}

Create a C# script Shake.cs and attach this script to the Camera game object:

public class Shake : MonoBehaviour
{
    ...

Define the fields:

[SerializeField]
[Range(0.1f, 0.5f)]
float range = 0.2f;

[SerializeField]
bool isShaking = false;

Vector3 lastPos;
bool hasLastPosHeld = false;

We will use the range field to control the "bounce" of the shaking and the lastPos to keep the last position, before the shaking.

Let's make our Camera to shake a little bit:

void Update()
{
    if (isShaking)
    {
        if (!hasLastPosHeld)
        {
            lastPos = transform.position;
            hasLastPosHeld = true;
        }

        float xPos = lastPos.x + Random.Range(-range, range);
        float yPos = lastPos.y + Random.Range(-range, range);
        float zPos = lastPos.z + Random.Range(-range, range);

        transform.position = new Vector3(xPos, yPos, zPos);
    }
    else
    {
        if (hasLastPosHeld)
        {
            transform.position = lastPos;
            hasLastPosHeld = false;
        }
    }
}

To simulate the shaking, hit play and change the Is Shaking via inspector to true. Cool, everything is shaking!
_{Note: Put something in the scene, in front to the Camera to have a better look of the effect.}
