FeLiNa Engine is a 3D game engine currently developed by:
- Alex Campamar, GitHub account Acaree.
- Alfonso Sanchez, GitHub account Siitoo.
- Project repository Felina.
- Website.
This engine have been developed in the design & development grade of CITM (Terrasa).
The objective is to develop a engine to use it in the next game we'll create.
The code is written in c++

Drag a file into engine: Copy the file in assets folder
-In assets window: - Double click on fbx: Add a fbx to the scene - Refresh Assets button: If a new file is in assets, generate all the needed files.
-In Hierarchy: -Left click: Focus a game object and show his properties in inspector. -Right click on gameobject: Delete option is showed. Delete game object on left click. -Right click not over a game object: Create new empty object option is showed. Create game object on left click
-In inspector: -Add component: Add a new component to the selected game object. -Inside a empty component, there is a place to drag a new material/mesh. The file dragged must be one of library (in assets window from the engine), others will be despreciated.
- Scripts:
- In assets folder, you can find a demo scene named "Assignment3.json". This scene contains a tank with a script to move it with i,j,k & l, rotate the turret with mouse motion in X-axis and shoot a ball (instance) with the mouse middle button.
- Create an script inside assets folder. Refresh assets and double click to open the node graph window.
- Right click: - In node graph, the add node option will be shown. - In a node, the delete option will be shown.
- CTRL+V: Duplicate the selected node.
- With left click you can create links between nodes (left anchors are for inputs and right anchors are for outputs. You can only link inputs to outputs). Left click over a node select-it.
- To close the node graph window, right click outside the node graph window.
- In the website, you can find gifs and a video showing how to use it -> https://acaree.github.io/FeLiNa-Engine/
- Add all nodes there (Right click->add and select the node type). Only event nodes can react to scene, so functions will never activate if there's no an event node before. A function node activated by other event node, can activate another function node. After putting all nodes, click compile button to save it.
- After that, drag the script to a game object script component (if the game object don't have it, you can create one script component in inspector). Open the graph from inspector and set all values and references.
- Nodes need to be edited in assets folder. After editing it, remove the script from all gameobjects that contains it and drag it again. You need to set all references & values again.
- Press play to execute scripts. If you open from inspector a game object graph, you can see the graph with the debug draw.
- Delete nodes (open it from assets in engine)
- Debug draw in node graph (open node graph in inspector while game mode is activated)
- Ctrl+V duplicate the selected node (graph must be opened from assets)
- Nodes have a checkbox active. If it's not marked, the node won't be executed.
- If a mesh have some triangle of his faces incomplete (with less of 3 vertices) whole mesh will be discarded.
- In inspector components only our own format files (files from library) can be dragged. We don't take responsibility if another type of file is dragged.
- Follow the instructions above to use and manage scripts. Before editing an script in assets, all references in game objects component script must be removed and dragged again. If a script is modified, save again the scene with the new script. If it's not saved, the scene will be corrupted.
