Mouse Key Board Text

Haiii sobat gacor pada kesempatan kali ini saya ingin membagikan sedikit ilmu yang sedang dipelajari yaitu tentang Menggabungkan Event Handling pada Mouse & Keyboard dengan Font & Text pada PyOpenGL

Contoh code :

from OpenGLContext import testingcontext
from OpenGL.GL import *
from OpenGL.GLU import *
from OpenGL.GLUT import *

# Koordinat x dan y untuk posisi kotak
pos_x = 0
pos_y = 0

# Warna Kotak
red = 0
green = 0
blue = 0

# Warna Teks
txtred = 1
txtgreen = 1
txtblue = 1

# Teks Warna Objek
warna_objek = "Hitam"

# Teks Warna Background
warna_background = "Hitam"
