The mechanic I spent the most time programming was the scrub tool. The engine we used didn't have a built-in mouse input feature for dragging the mouse around. We wanted to include this feature to make the players more immersed into the actions of cleaning like the character. To develop the tool I created a mini mouse FSM that checked the activity of click & release to find the position of the first click within the blood sprite. The click I tracked was used as a reference to compare the mouse positions over the course of 30 frames to see if the user was actively scrubbing away at the blood with their mouse. If they were, the sprite's opacity would lower. This looped until the declared duration for when the sprite would be completely gone was reached.

     The amount of frames to lower opacity and total duration can easily be changed as I set them as a parameter for a second constructor. The first constructor sets their default values to 30 frames & 90 frames. The parameterized constructor was made in planning for possible future development, where we would want a variety of larger stains (ex. spilled drinks) that'd take longer to scrub away at.
