Learn unity programming with c sharp by creating a scripts folder and a player script, attaching it to the player, and computing c = a + b with debug log.

Fix the jump by adding a ground check sensor at the player's feet and use a ground layer with an overlap circle to allow jumping only when grounded by spacebar.

Set up the animator controller to transition between walking and jumping with a ground boolean, zero duration, and no exit time, then drive it from code.

Set up a working health system with spikes as obstacles, a player health script managing current and max health, applying damage on collision, and deactivating the player at zero health.

Set up spikes in Unity with a box collider 2D set as isTrigger, tag the player, and implement a damage script using a singleton to call on trigger enter.

Add animated checkpoints in Unity 2D runner by creating a flag sprite, configuring a box collider 2D trigger, and updating the player's checkpoint position via a script for reliable respawns.
