| - **Before we start** there are some basic changes that have to made to the environment, in order to make the physics look more realist, we must make sure that our environmet is in a logical scale. If you have the handout code, Sinbad will be around 9.5 units high, Bullet library uses 1 unit as equal to 1 meter. | - **Before we start** there are some basic changes that have to made to the environment, in order to make the physics look more realist, we must make sure that our environmet is in a logical scale.

| - **You can check out Sinbad's actualt height** by doing ''_SinbadNode->getBoundingBox().getSize()'', this function will return the bounding box the the sceneNode, which is an axis aligned box that encompasses the entities of the SceneNode and is defined by the vertex extremas + an additional 2% scale. | - **You can check out Sinbad's actualt height** by doing ''_SinbadNode->getBoundingBox().getSize()'', this function will return the bounding box the the sceneNode, which is an axis aligned box that encompasses the entities of the SceneNode and is defined by the vertex extremas + an additional 2% scale. |
