ive got the code in but i get this error after i try to use the attack

$$anonymous$$issingComponentException: There is no 'ParticleEmitter' attached to the "$$anonymous$$uscular" game object, but a script is trying to access it. You probably need to add a ParticleEmitter to the game object "$$anonymous$$uscular". Or your script needs to check if the component is attached before using it.
