A simple script that will give a short, blurry motion trail effect.
In a control object, you can assign every object you want to have blur in an array, and the code will do the rest. To keep performance, it will only activate when the speed of the object is more than 0, but it would be wise to use this with care, aka don't have a thousand objects on screen active with this effect. Other than that, it should be fine. Also, if your game runs at 120fps, it will look twice as good, and the inverse if it runs at 30 fps.
Here you have a little gif to see somehow how it works
