test out the sliders and see what they do the red points are (rx, ry) and (zx, zy) rd is the amount of degrees to rotate rx is the x value of the point rotated around ry is the y value of the point rotated around shift x moves the x value of everything before the rotation and zoom shift y moves the y value of everything before the rotation and zoom z is the amount zoomed (1 = default value) zx is the x value of the point zoomed into zy is the y value of the point zoomed into tshift x moves all the x values after rotation and zoom tshift y moves all the y values after rotation and zoom order of operations shift x and shift y rotation zoom tshift x and tshift y
made from scratch (pun intended) to use, backpack the pen sprite and put it in a project no credit needed, please just go to my profile or this project and comment the link because i would love to see what people do with this
