athena's Issues

Add a cheat mode

The console module has support for registering "cheat" cvars. We need a mechanism to enable a cheat mode to enable these commands

Multithreaded logging

Would be great to handle logging on a separate thread. There's no need for the game engine to wait for the console library to write the text to file before advancing a frame

Entity parenting

Entity parenting would allow an entity to be attached to another entity and travel with it as the parent moves around. In order for this to work, the following would need to occur.

• Update the entity class to include a parent entity id
• Write a function to calculate parent position + child position
• Function on a parent that can return all children

Virtual filesystem

Add a virtual filesystem implementation using PhysFS. Prerequisite for mod support

Multiple mouse events are being handler per frame

It looks like we're receiving an SDL mouse move event for every pixel the mouse travels. We're then triggering the mouse move event in the engine for each of these SDL events.

This may cause performance issues since we're handling more events that we need to. It would be better if we could bundle these events together somehow

Collision system

Create a new system and component that can be used to handle collisions.

This would involve creating a collision system, collider component and onCollided script events.

• onCollided event
• Prevent collided entities from intersecting
• Collision mask to allow for filtering
