If you require advice or assistance choosing the correct version of Game Maker, please contact Texchellent on info@techxellent.com.au

This course consists three modules. It begins with the applications of object oriented programming to create new elements (gems) which build on the properties of previously created elements. The course then goes on to create monsters which have their own unique movement dynamics and collision conditions which deplete the health of our explorer. Then we cover the creation of multiple levels and 'portals' which take the explorer from level to level.Next we tackle some advanced concepts like the creation of a new monster which has the ability to sense a clear path and chase the explorer. Finally, we explore animations and program in some realistic movement animations and explosions. Below is a specific set of student outcomes for this module:

Parent-Child Relationships Between Objects:

  • Explain the purpose of a parent-child relationship in Game Maker.
  • Configure parent-child relationships between objects.
  • Create child gem objects of different colours and program them to act as the parent gem.
  • Create groups for your sprites and objects to organise them.
  • Explain how the Test Instance Count Question works.

Creation of Monsters With Basic Artificial Intelligence:

  • Create monsters which move horizontally.
  • Program the monster to reverse its direction when it collides with a wall.
  • Program a collision between the explorer and the monster which makes the game restart.
