Life Stealer - Procedural walker feature

Life has a new enemy with legs, AI and terrain hugging abilities. It is not a robot you want near your plants :-)

The walker use Unity IK rigging and animation with a VFX for flames and particles. Here is the code controlling the body so it angles itself in relation to the legs with smooth and deadZone.

public Transform footLB;
    public Transform footLF;
    public Transform footRB;
    public Transform footRF;

    public float rotateMultiplier = 1f;

    public float currentXrot;
    public float currentZrot;

    public float targetXrot;
    public float targetZrot;

    public float rotPerFrame = 0.1f;
    public float deadZone = 0.2f;

    // X is back front
    // Z is left right


    // Update is called once per frame
    void Update()
    {
        float avgLeft = footLB.localPosition.y + footLF.localPosition.y;
        float avgRight = footRB.localPosition.y + footRF.localPosition.y;

        float avgFront = footLF.localPosition.y + footRF.localPosition.y;
        float avgBack = footLB.localPosition.y + footRB.localPosition.y;

        targetXrot = (avgBack - avgFront);
        targetZrot = (avgRight - avgLeft);

        if (targetXrot - deadZone > currentXrot)
        {
            currentXrot += rotPerFrame;
        }
        if (targetXrot + deadZone < currentXrot)
        {
            currentXrot -= rotPerFrame;
        }

        if (targetZrot - deadZone > currentZrot)
        {
            currentZrot += rotPerFrame;
        }
        if (targetZrot + deadZone < currentZrot)
        {
            currentZrot -= rotPerFrame;
        }

        transform.localEulerAngles = new Vector3(currentXrot * rotateMultiplier, transform.localEulerAngles.y, currentZrot * rotateMultiplier);
    }

Here you can see the terrain painter in action as the plants are consumed by the walker.

The end result with nav AI and plant range finding. And a rough terrain manipulation. I hope to make it using masks instead of handcoded pixels.
