Make a button
To create a button we simply call the following function.
ui_button_create(x, y, width, height, text);
Where x and y are the position of the button is placed, the width and height are the width and height of a button. You can use macros ui_default if you want to use autofit size corresponds to the length and width of the button text. And finally we can add text buttons with text argument.
buttonLogin = ui_button_create(32, 64, 128, ui_default, "LOG IN");
The above line of code is used to create a button with the "LOG IN" text at certain positions with a width of 128 pixels and adjust the height to the height of the text button.
