api clamp
The Clamp() API limits a value between a minimum and maximum integer.
Clamp ( val, min, max )| Name | Value | Description |
|---|---|---|
| val | int | The value to clamp. |
| min | int | The minimum value should be. |
| max | int | The maximum value should be. |
| Value | Description |
|---|---|
| int | Returns an int within the min and max range. |
In this example, we will increase the number by 1 every frame and clamp it at 100.
Running this code will output the following:
local counter = 0
local time = 0
local delay = 300
function Init()
-- Example Title
DrawText("Clamp()", 8, 8, DrawMode.TilemapCache, "large", 15)
DrawText("Lua Example", 8, 16, DrawMode.TilemapCache, "medium", 15, -4)
end
function Update(timeDelta)
-- Add the time delay to the time
time = time + timeDelta
-- Check if time is greater than the delay
if(time > delay) then
-- Increase the counter by 1
counter = Clamp(counter + 1, 0, 10)
-- Reset the time
time = 0
end
end
function Draw()
-- Redraw the display
RedrawDisplay()
-- Draw the counter to the display
DrawText("Counter " .. counter, 8, 32, DrawMode.Sprite, "large", 15)
