Code: Select all
if (mx > x) and (mx < x + w) and (my > y) and (my < y + h) then -- point is inside the boxX and Y are known as you placed the button in question before, right?Midhun wrote: ↑Sun Dec 01, 2024 12:58 pm Do u mean that x and y is the position in top left of the button or the position of the button(midpoint of the button)???
Also how do we find the x and y of the top left corner of the button if yes to the first question.
By the way thank you so much for telling me how to do this.
This will be off by one pixel, though. Clicking exactly on the left or top border of the rectangle won't register the click; you need to be 1 pixel inside the left or top border for this to work.darkfrei wrote: ↑Fri Nov 29, 2024 11:21 am Simple version:
The button has top left corner in x, y and width, height w, h.
On the click check if the mouse position mx, my is inside the rectangle of button.Code: Select all
if (mx > x) and (mx < x + w) and (my > y) and (my < y + h) then -- point is inside the box
Yes, the better solution needs more logic: array of buttons, highlight the hovered button, select not all hovered, but the top of them, dynamically adding/removing buttons, the texture, text, rounded corners etc.
Code: Select all
