How to make particles follow the camera?

Hello everyone, So I have this system for a project in paper2D, it is suposed to spawn a particle system on touch position Fruit Ninja’s style which works perfectly when camera is still, but when character is moving it gets all messy, so my question is: How can i spawn my particles and keep then on screen while the character is moving, and yet still make them responsive to swipe speed?

Thank you.
