i had to golf this code to get the original d/19898 under 140, but lost the "focal point" effect achieved here. In need of a shorter way to compute the (euclidean) distance from the focal point (defined by "d" in the code).

please excuse my poor etiquette for i have now learned about code blocks and replacing EVAL with THROW to display compressed code, and the Discord for chat : )

Getting mouse position. Can someone make it in less characters ?

u/tomxor

c.onmousemove=e=>{c.x=e.x,c.y=e.y};x.fillRect(c.x-25,c.y-25,50,50)
u/tomxor

Even smaller: c.onmousemove=e=>R=e x.fillRect(R.x-25,R.y-25,50,50) R can be any existing object of course
u/tomxor

Oh also can define global mousemove event rather than on c: onmousemove=e=>R=e;x.fillRect(R.x-25,R.y-25,50,50) pretty sure that's as far as it goes, -44 chars
u/tomxor

If you are happy without full screen you could also ommit the width/height and multiply by an appropriate constant: c.width|=onmousemove=e=>R=e;x.fillRect(R.x*3.4-25,R.y*3.4-25,50,50) that's -73, now you have some space to do something.
