Unity Game Development Master Class

Implement a half-second cooldown and ammo counter: track cooldown with delta time, allow shooting only when cooldown is zero, spawn bullets, and start with 20 ammo shown in the UI.

Attach a nav mesh agent to the enemy, set speed and destination to the player, update the destination in the update function, and stop the agent within 1.5 units.

Master the animator-first workflow by recasting the animation timeline, adding events, and applying ray casting from the camera with baked navmesh, agents, and enemy patrols to manage damage.

Move the camera in a top-down Unity game by following the mouse at screen edges and center it on the player with space, enabling smooth follow when held.

Import 3d models into Unity by downloading assets, importing the model file and textures, creating materials, attaching the model to the player, and turning it into a prefab for animation.

Follow the player with a y-axis offset and a z-axis offset for smooth camera movement. Use late update to apply the camera target offsets, enabling forward/backward, up/down, and left/right movement.

Hold right mouse button to rotate camera around the player, using mouse X and Y, clamp vertical rotation to -30 to 30, and apply quaternion rotation to the offset.

Implement enemy logics using a state machine to handle idle, standing up, and attack states, with a character controller driven forward movement and animator integration that activates on aggro.

Apply the singleton design pattern to create Unity game manager that coordinates saving and loading, serialize int, float, and string, convert Vector3 to three floats, and implement local save system.

Add a second player by duplicating the player and assigning materials, and implement per-player input with an enum id and keyboard and gamepad mappings for movement, jumping, and animation.

Improve weapon logic with recast to stop the line render at impact and display impact marker. Update line render positions and toggle an impact pos sphere on hit, preparing shooting.

implement advanced animations by triggering shoot and reload via the animator, manage is_reloading state and reload behavior, and add crouching logic with is_crouching to control movement and animation.

Implement inverse kinematics in Unity to attach the left hand to the weapon using humanoid rigs, set position and rotation weights, and disable IK during reloading.

Implement advanced impact marking in Unity by placing a plane at the collision point with a slight offset and correct normal, then texture it and create a gunshot crack prefab.
