Hi i am totaly new to Unity. I am going to start a Phd in simple machines VR and i want to create simulations of machines such as catapelts, steam machines, hand pumbs and others. I want to design these machines and simulate the function. Thats why i want to make the work with triggers. For example, if the gamer starts the fire, smoke creation and gears move... Is it difficult to create such mechanics simulation with Unity Engine
