Quil Mouse Clicks

2023-06-22

In my Traveling Salesman point picker, I am using the graphics library Quil to display graphics. Quil also handles user input like key presses and mouse clicks. Previously, I was using a bad method of managing mouse presses. Every frame, I was simply checking if the mouse was clicked, and if it was then I would do what I want. This caused some problems because for reasons like framerate, some mouse clicks would not be registered because they were not done close enough to the call of the update function. But there is an easier way. Quil actually comes with a mouse-clicked event bind that event works with fun-mode. You can define what function you want to be called by adding :mouse-clicked my-function to the parameters in the defsketch. In fun-mode (functional mode), my-function should take in two parameters, one for the current state and one for information about what button has been pressed and where. Whatever is returned from the function is also used as the new state for the next frame.
