GamePlay3D - common error messages

Some common error messages you might encounter when developing a game with GamePlay3D, and how to solve the issues:

Attempting to set a material on node ... which has no model

Symptom

After creating a new project, copying the source code from the character sample and running it, you get:

applyNodeProperty -- Attempting to set a material on node 'boymesh', which has no model.Assertion failed: (0), function applyNodeProperty, file /Users/frank/src/GamePlay/gameplay/src/SceneLoader.cpp, line 246.

Cause

Resource file is missing

Solution

Copy the missing resource file to your project directory (I ended up copying the whole res/ folder from the example project)

Texture sampler ... is missing required image file path

Symptom

After creating a new project and copying the source code from the longboard sample and running it, you get:

loadRenderState -- Texture sampler 'u_diffuseTexture' is missing required image file path.

Assertion failed: (0), function loadRenderState, file /Users/frank/src/GamePlay/gameplay/src/Material.cpp, line 418.

Cause

game*.config files missing

Solution

copy the game*.config files to the app directory
