Hi,
after some time, I've created a new video demonstrating the current state. In the last months, I was busy implementing some basic script components, re-implementating the UI and adding simple AI-Bots. The script components are responsible for displaying the ingame-UI (interaction toggle for buttons, etc.) or switching the lights. The new script components uses the new UI-features for displaying the toggle-menu. The new UI is more flexible in rendering elements and can render itself in perspective mode, which is usefull for 3d-menus floating inside the world.
The biggest part was the implementation of the AI. First, I've implemented navigation meshes with path finding. It is far from done and sill has a few mayor bugs, but the general idea works until now. The second part for the AI was the "intelligence". The bots are controlled by a behaviour tree, written in script. The bots can only "see", so they do not react on the world yet (sounds, light switches, gun-shots, etc.). In this demo, they simply walk around randomly, which makes them quite challenging. But they are still harmless, because the player does not have any health yet, so any gun hit will result in: nothing.
So this is the current state, hope you enjoy it.
