Project Stealth

When designing the main movement script, we wanted it to be physics based so we could achieve a more realistic feel for the player. This controller allowed the user to walk around, run, crouch and slide. All features we would want to make use of within a stealth game.

Below is the first part of the movement script, where I took the user's inputs and applied the appropriate reaction, getting these inputs from Unity's input system.

Below is the main movement function. This controls and applies all movement to the player. Fristly, it find the player's velocity relative to the direction the player is looking, then applies the relevant CounterMovemnt, passing these velocity values. We then check whether the player is wanting to jump, and apply the jump if needed, if I was writing this script again I would separate this into it's own method to be called directly from the button press. We then check whether the player is crouched, ensuring to add a sliding force so they can slide down ramps and steep declines. The method then checks whether we have reached the max speed, ensuring more force is not added to the player if the maximum speed has already been reached. Finally, in this method, a directional force is applied to the player in the input direction.

This method applies an apposing force to the player, simulating friction. Firstly, it returns out of the function is not grounded since this is to simulate the floor friction. Additional counter movement is then applied if sliding. After this, the main counter movement is applied to the player in the opposite direction of movement. I then wrote a small if statement to limit diagonal running speeds, setting the player's velocity directly if travelling too quickly

There are many different things I would change throughout this script to improve it, such as adding the hardcoded values as variables, separating large methods into smaller ones to keep the code cleaner and more organised, and other general improvements.

The drones roaming around the levels in the game were to be a big obstacle to the player, having them patrol given areas, go towards the player if they were seen for a short amount of time, and getting effected by the hack feature available to the player. This drone made use of Unity's NAvMesh and NavMeshAgents.

Below are some of the main methods within the AI script, controlling which patrol point the drone is to move to and changing the drone's active behaviour state. The MoveBetweenPoints method controls which point the AI is actively moving towards, changing to the next point whenever it reaches this point and circling back to the initial point when the final destination is reached.
The Investigate method changes the dronestate to investigating and makes the drone search the last known location of the player.
The HackDrone method handles the drone getting hacked, changing it's behaviour depending on whether it is controllable on not.

This switch statement is found within the update method, controlling what the drone is doing depending on it's behaviour state.
If the dronestate is patrolling, it calls the MoveBetweenPoints function so it can continue patrolling its designated area.
If the dronestate is investigating, it checks whether it has reached the player's last known position, in which when it does it will continue patrolling if the player isn't seen again.
If the dronestate is hacked, the drone is swtiched into it's hacked state, allowing the player to control it if applicable, and keeping the drone hacked for an amount of time.
