I used the browser extension to set the crosshair sprite to where the mouse is. Then, I used the sprite utils extension to get the angle between the player and the crosshair. Lastly, I used an image transforms extension I found on awesome arcade and rotated the gun sprite towards the crosshair.
If you want a more in-depth explanation, I will touch on it in my next RUNE LOG.
thanks I checked the game code to get a little more in depth explanation and stol- I mean copied it (jk) The way you did bullets actually makes it really easy to make spread.
