Learn To Create a Tower Defence Game With Unity & C#

Automatically locate the path object and propel an enemy along its points, updating the current point and stopping at the end to ensure smooth navigation.

Assign each spawned enemy a specific castle and path using a setup function and null checks, preparing for future support of multiple paths and castles.

Set up attack points on the castle and have waves of enemies randomly target these points, spreading the siege while moving toward selected positions using Unity C# scripting.

Stop enemy movement and spawning when the castle's health reaches zero by gating the enemy controller with health checks and using a public castle health variable with inspector visibility control.

Learn to detect enemies in range by collecting their enemy controllers into a list using a for each loop to get components, and optimize updates with a timed check.

Implement a money system with a money manager singleton, track current money starting at 200, and award 50 gold on enemy death to fuel tower purchases.

Display a red not enough gold warning in the UI when the player lacks funds to place a tower, toggled by money checks against the tower cost.

Implement a level manager to determine win or lose by monitoring the castle and active enemies. Add and remove enemies as they spawn and die to trigger level completion.

End the level by deactivating tower buttons through the UI controller to prevent further purchases, then run the level complete system and show remaining gold.
