The example shows three different types of progress indicators:
progress.gui_script
-- set the width of the horizontal progress bar local function update_horizontal(p) local node = gui.get_node("horizontal") local size = gui.get_size(node) size.x = p * 400 -- max width is 400 pixel gui.set_size(node, size) end -- set value of numeric progress indicator (in percent from 0% to 100%) local function update_numeric(p) local node = gui.get_node("numeric") local percent = math.floor(p * 100) gui.set_text(node, tostring(percent) .. "%") end -- update radial/circle progress by changing the fill angle local function update_radial(p) local node = gui.get_node("radial") local angle = p * 360 -- full circle is 360 degrees gui.set_fill_angle(node, angle) end function init(self) self.time = 0 end function update(self, dt) self.time = self.time + dt -- calculate a value between 0.0 and 1.0 -- the value will gradually increas from 0 to 1 during 3 seconds local p = (self.time % 3) / 3 update_numeric(p) update_horizontal(p) update_radial(p) end
