Is the a way that i can attach a particle emitter to each torso [disabled] then when the f key is pressed the particle emitter is enabled?
This is a pretty simple task. When you insert a particle emitter into a part the emitter is now "attached" to that part. If you want to change how it behaves then you need to change the properties of it.
More on Particle Emitters here.
In order to get the particle emitter to activate when the player presses "F", you will need to use the UserInputService in a Local Script.
