window

v0.0.6
createWindow(w, h);

Create a GLFW window.

Arguments

wWindow width
hWindow height

It is also possible to create a window in the global scope without defining a setup function.

 function setup()
   -- Create the window here
   createWindow(600, 600);
 end

 function draw()
   -- draw things
 end

frameRate(fps);

Set the frame rate

Arguments

fpsThe frame rate to set

If frame rate is called without an argument, it will return frame per seconds 

 x = 0;

 function setup()
   createWindow(400, 400);
   frameRate(24);
 end

 function draw()
   background(51);
   text('fps: ' .. frameRate(), 20, 10);

   circle(x, 200, 32);
   x = x + 1;
 end

deltaTimeGlobal

Elapsed time since the last draw call in seconds

 x = 0;
 vx = 128;

 function setup()
   createWindow(400, 400);
   frameRate(24); -- try with 60
 end

 function draw()
   background(51);

   circle(x, height/2, 32);

   -- Get the same velocity with different framerates
   x = x + vx deltaTime;
 end

widthGlobal

The window's width in pixels. If no window was created, this value is nil

 createWindow(800, 600);

 print(width);
 -- 800

heightGlobal

The window's height in pixels. If no window was created, this value is nil

 createWindow(800, 600);

 print(height);
 -- 600

windowResized();Event

Called when the window is resized

 function setup()
     createWindow(500, 500);
 end
 
 function draw()
     background(51)
 end
 
 function windowResized()
     print('Resized!')
 end
