const pc = 1 // make pc 2 if on pc


let samples = Array.from({length:512*pc},()=>-1)

function write(x,y,value){
	// value being true means write that pixel
	// else make it black
	// x ranges from 0 to 1 apparently
	// y ranges from -1 to 1
	// ik its weird but im too lazy to fix it at this point
	if (value) {
		samples[floor(x*512*pc)]=y
	} else {
		samples[floor(x*512*pc)]=-1
	}
}

// example usage down here V
return (t,s)=>{
	// every second we draw a random pixel on the screen
	if (t%1==0) {
		write(random(),random()*2-1,true)
	}

	// get sample and output
	return samples[floor(t*s)%(512*pc)]
}
