HOW TO USE IT

Shaders

The last assignment for the engines class was to incorporate shaders in the engine. Here is how it works:

1- Drop the vertex program and/or fragment program to import it. There is a message in the console with the result of the compilation. 2- Go to Window/MaterialCreator 3- Write the path to save the material. Ex: /Assets/test.mat (Must have .mat extension) 4- Choose the vertex and fragment program to use 5- Add all the uniforms that the shader is using. If it's a sampler2D select an imported texture or rendertexture. 6- Click create shader. The result message shows if it has been successful. 7- Select a gameobject with a mesh and material and change the material.

All objects uses the default shader if no material is specified. The default shader uses:

• Diffuse texture (if has)
• Normal map (if has)

Editor movement

• Move the camera with arrow keys

• Move the camera with the mouse wheel pressed

• Zoom in/out with the mouse wheel

• Left Alt + Right mouse orbit the camera (Needs improvement)

• Left Alt + Left Click to select an Object

• Left Ctrl + S to save a scene

Menu Options

File:

• Create New Scene: removes the current scene and creates an empty one Edit:
• Camera: show the editor camera options. If the scene has at least one camera it's possible to switch the editor camera to one in the scene
• Shaders: wip. The last input option shows a texture loaded in memory by it's id.
• Lighting: ambient light configuration
• Layers: create new layers or rename.
• RenderTexture: configuration of a render texture

Windows:

• Configuration: configuration of the editor windows
• Console: Displays the console
• Profiler: Displays the profiler.
• Assets: it's open by default.
• Resources: shows the amount of resources loaded in the GPU.
• MaterialCreator: to create a new material. Debug:
• Show/Hide Octree: draws the boxes of the octree.

Hierarchy

Right mouse click on the window to show the options:

• Create Empty GameObject
• Create Empty Child: inside the selected GameObject
• Remove selected GameObject

Inspector

• Click on the name to change it
• Right mouse click to add a new component

Note: all components need to have first a transform component attached. Do NOT try to add a component to a GameObject which it's parent doesn't have a Transform component Do NOT change the position of a static GameObject.

Play/Pause/Next

Press play to start the game simulation. Pause to Stop (and play again to continue). Press stop to end the simulation.

Note: Next button doesn't work yet.

Import New Files

Drag and drop files and/or folders to the application.

Accepted formats:

• Images/Textures: png and tga
• Meshes: fbx and obj

Assets Window

Left click on a folder/file to show the options. It is possible to modify a texture or mesh and the editor automatically reimports the new files.
