unity explosion 3d

AddExplosionForce(float explosionForce, Vector3 explosionPosition, float explosionRadius, float upwardsModifier = 0.0f, ForceMode mode = ForceMode.Force)); // Example public float power = 10.0F; Vector3 explosionPos = transform.position; public float radius = 5.0F; Rigidbody rb = GetComponent<Rigidbody>(); if (rb != null) // Check if object have component "Rigidbody" rb.AddExplosionForce(power, explosionPos, radius, 3.0F);

        var explosionDir = rb.position - explosionPosition;
        var explosionDistance = explosionDir.magnitude;

        // Normalize without computing magnitude again
        if (upwardsModifier == 0)
            explosionDir /= explosionDistance;
        else {
            // From Rigidbody.AddExplosionForce doc:
            // If you pass a non-zero value for the upwardsModifier parameter, the direction
            // will be modified by subtracting that value from the Y component of the centre point.
            explosionDir.y += upwardsModifier;
