Bug fixing

Find out why the RhythmTimer ends up being off-beat sometimes.

See RhythmTimer.cs. Changed the way it works such that it now uses beats instead of seconds when deciding if the player clicking “on beat”. It seems to be more precise than before.

Prevent projectiles from passing through walls. Always.

See Assets/Prefabs/Bullets/Player Projectile.prefab. This prefab has two child game objects, and the one named “Bullet” had a very small Capsule Collider, which meant that at high speeds it wasn’t registering collisions with walls. We changed that into a Mesh Collider which gets recalculated every time the mesh of the object changes (so it’s accurate for all projectile types).

Make enemies roll on the ground rather than levitate.

This was fixed by modifying the Base Offset of the enemies’ Nav Mesh Agent (from 1 to 0.25). The enemies still sort of glide on the ground, and sometimes clip through it when spinning, but we’re satisfied with this kind of movement for now.

Fix new projectiles orbit bugs.

See commit 5d1a97e5e7597f3618f8534ce1b92821252bf34f. The order of operations was wrong, now the orbit moves as intended.

New stuff

Add particle effects on evolution.

The player has a child object with a Particle System component which rotates such as to counter the player’s rotation (to always point upwards, regardless of the player’s movement).

See Scripts/RestoreRotation.cs, Evolvable.Evolve, Prefabs/Player.prefab, Prefabs/Player Evolution Particles.prefab.

Add particle effects on bullet collisions.

Explosions (game objects with particle systems – Prefabs/Bullets/Bullet Explosion.prefab) are kept in an object pool and spawned when a player’s bullet collides with something.

See Projectiles.Bullet.OnTriggerEnter, Scripts/Projectiles/BulletExplosion.cs, Scripts/ExplosionPool.cs.

Change rhythm system so that shooting on beat increases the damage, but you’re allowed to shoot anytime.

The player’s damage gets higher the closer the moment when they shoot is to the beat.

See InputController.HandleShootInput.

Add a menu.

We added a game over screen, the main menu, an options screen and a pause overlay.

See GameManager.Update, GameManager.PauseGame, GameManager.ResumeGame, GameManager.GoBackMain, Player.CheckStatus. Pausing is implemented by stopping time flow (Time.timeScale = 0f).

Spawn enemies in waves.

See GameManager.NextWave and GameManager.SpawnEnemies. The number of waves per level and enemies per wave is configurable.

Progress to next level when the player has defeated all waves.

See GameManager.NextWave and GameManager.ProgressToNextLevel.

Prevent enemies from spawning in walls, maybe with predefined spawn points in each map.

We check if the spawned enemy would collide with anything that isn’t the floor by projecting a sphere from it’s spawn point.

if (Physics.CheckSphere(randomPosition, 0.7f, (int) Layers.Floor))
{
    continue;
}

See GameManager.GetRandomPosition.
