Hey, as no one made a motion blur effect for construct, I'm trying to do it on my own.
I've made some researches on how the effect should work, and I found that what the effect does is:
1- Copies the canvas (or whatever name you call it, the part of the game that is currently displayed on screen)
2- Adds to it some blurry effect
3- After 1 frame, blends it to the current canvas
4- Go back to step one.
So, I know how to blend images.
I kinda know how to add that blurry effect.
But, the whole problem is that I neither know how to "copy" the canvas nor how to "wait" 1 frame
