// I use this to force the cursor to be a crosshair in diep.io as I think it's better for aiming than the arrow cursor.
// Just copy and paste this code snippet bellow in the browser console.
// The need for checking every 20s comes from the fact that the cursor is reset when hovering buttons (e.g. tank upgrade buttons).
// Cheking every 20s is quite smooth and does not decrease the game's performances.
// Alternatively, it's possible to opt for "move" instead of "crosshair" to get a fatter cross.

	if (document.getElementById("canvas").style.cursor != "crosshair")

PowerShell Tips

Write-Host vs Write-Output

Write-Host writes directly to the console; Write-Output writes to the pipeline, which often ends up to the console but not necessarily.

For example: Write-Host "The Cake is a lie" | Out-Null won't work as expected, Write-Output "The Cake is a lie" | Out-Null will.
