Tower Defense¶
Tower Defense is a minigame which is part of the Gamify-IT platform.
About the Game¶
The intention with this game is to make answering single choice questions fun but.
In comparison to other minigames, Tower Defense provides a more complex and longer effort.
When entering the game, the user is presented with the main menu. After pressing the start button the enemies start spawning. The player then can place towers along the road to kill the enemies. Everytime the player wants to place a tower he must answer a question correctly to do so.The player also can upgrade the towers to make them stronger, for each upgrade he also must answer a question correctly. Once too many enemies reach the base the game ends. The longer the player survives the more points he can earn.
Configuration¶
The lecturer can configure the game with an arbitrary number of questions.
Each question has a single correct answer and an arbitrary number of wrong answers. The lecturer can also configure the time limit for the game.
For more information how to configure minigames see the lecturer interface manual.
User Interface¶
The game will open with the start menu. There, you can choose to either start or exit the game.
When you start the game, the game map with the UI elements will be loaded. In the top right-hand corner you have a pause button and a speed up button. You can switch between standard pace and double pace. On the other side to the buttons, there is a life bar representing your current amount of health points.
At the beginning of the game, the shop menu is expanded allowing you to choose between towers with different attack styles. In the top left-hand corner of the shop menu you can see the current amount of currency available to you. After left-clicking on a tower you can move the cursor to the preferred position on the map and place the tower by left-clicking again. You can collapse the shop menu by clicking on the shop icon at the right-hand side.
Game Mechanics¶
Win Condition¶
In Tower Defense, there are two conditions to finish the game:
When your life is empty, the game ends and you will be directed to the game over screen, where you can return back to the overworld or try again.
If you answered all questions, the game will end after the current wave has finished. Then, you have the opportunity to see your results.
If you answered all questions, the game also ends and you have the opportunity to see your results.
Upgrading Towers¶
If you click on a tower, there will appear an upgrade menu that enables you to improve the tower’s defense properties. Before you can upgrade a tower, you need to have enough coins and to correctly answer a question. If your answer is wrong, the upgrade price is still lost, so answer carefully but also quickly since the game is not paused!
