Wereldgenerator

Door Michael R -18-01-2015 21:08 -13.880 views

Een script die een wereld genereert met aansluitend water en land. Ook geeft hij de coördinaten per vakje aan. Plaatjes moet je zelf toevoegen in de map: 'images'. Noem de plaatjes: texture_grass.jpg,texture_water.jpg,texture_sand.jpg. Maak een database aan genaamd 'worldmap' en voer daar de sql code uit.
