Lecture Details

This time, my game mainly uses the following physics functions:

• AddForce(): Apply force to enemies in ForcePulse.cs to create a push effect.
• Physics2D.OverlapCircleAll(): detects all physics objects within the range of the force field
• ForceMode2D.Impulse: applies instantaneous impact force
• OnCollisionEnter2D(): Handle collision detection between enemies and player.
• Rigidbody2D: All dynamic objects use a rigidbody component to ensure physical interaction.
• Custom Physical Materials: Adjust elasticity and friction properties.

Meanwhile, I showed different applications of the physics mechanism in three levels:

• Level 1: Basic Force Pulse mechanic where the player needs to repel enemies
• Level 2: Introduces a Ball Launcher, adds physics interaction options, and allows the player to launch physical balls.
• Level 3: Combination of the first two levels' mechanics, adding Danger Area that require a combination of skills

Design Details

Balance

Game balance is achieved through:

• Force Pulse have a cooldown
• Ball Launcher limit the number of balls that can be present at the same time
• Enemy waves gradually increase in difficulty
• Force Pulse are both a defensive and offensive tool, and players need to weigh when to use them

Communication

The game provides a clear feedback mechanism:

• There is a visual diffusion effect when the Force Pulse is released
• The health value UI intuitively displays the player's status
• The physical response when the enemy is repelled provides a sense of satisfaction
