First Program

Let’s write a simple test program, create a new file named test.py and paste the following code into it.

import harfang as hg


win = hg.RenderInit(400, 300, hg.ResetNone)

while not hg.ReadKeyboard().Key(hg.K_Escape):
	hg.SetViewRect(0, 0, 0, 400, 300)
	hg.SetViewClear(0, hg.ClearColor, hg.RGBA32(96, 32, 255))




When executed, this program demonstrates how to create an output window, initialize the input and render systems and paint the whole window in blue until the escape key is pressed.

In order to draw anything on screen we will need to create at least a shader and compile it before using it in our program, this process is documented in the Resources & Assets page.
