If we start working with the Blender Game Engine (BGE), we must have a library of all of the objects we use in our game. For example, the basic character, or even the smallest details, such as the appearance of health levels of our enemies.
On the Internet, we can find plenty of 3D objects, which can be useful for our game. Let's make sure we use free models and read the instructions to run the model. Do not forget to mention the authorship of each object that you download.
Still, we know that we can open files in Blender and what needs to be imported. A few lines in the following section explain both these ways, step-by-step.
