Weather effects should be highly visible and immediately recognizable, using 300 particles, but not interfere with game collision detection. Consider performance optimization strategies when implementing weather particle system. |
task-12 | 2025-05-12T00:00:00 | moderate | When the weather is Night, a new item type 'Coin' is provided: it is shaped like a yellow concentric circle. After obtaining it, the score increases by 10. When the weather changes back to others, the existing Coins will also disappear immediately. |
task-13 | 2025-05-12T00:00:00 | easy | When the weather is 'Rain', the bird's jumping speed slows down to 0.8 times, and the falling speed becomes 1.2 times the original. When the weather is 'Wind', the overall forward movement speed becomes 1.5 times. |
task-14 | 2025-05-12T00:00:00 | challenging | Every 5 seconds, there is a probability of generating an elliptical gravity field on the ground, with the height of the ellipse center at ground level, moves with floor. The width of the gravity field is three times the pipe spacing, height is 40, with a probability of 'store.fieldRandomRate' (default value 0.25, variable). The data of the field stores in 'store.field', and there will only be one field on the canvas at the same time, when the x of the bird is within the range of the field, it takes effect. The field type 'Zero': has a color that transitions from blue on the outside to black in the middle, The entire field glows with obvious special effects, the effect is that the bird's velocity will not > 0 within this distance. |
task-15 | 2025-05-12T00:00:00 | challenging | Periodically spawns enemies at random vertical positions on screen's right edge, generate one per second, stores in 'store.enemies', with maximum 10 simultaneous enemies. Enemies move to left at constant horizontal speed 6 while having random initial vertical velocity (range -0.5,0.5 ). On collision with bird, reduces player life. Enemy sprites use mirrored and color-inverted version of 'assets/bird.png', pre-rendered using offline canvas for performance. Note: Do not forget to implement the new method. |
task-16 | 2025-05-12T00:00:00 | easy | Additional control options: 'arrowDown' and 's' triggers rapid descent speed 6, 'arrowRight' and 'd' activates speed-up mode affecting all game elements, while 'w'、 'j' 、 'space' and 'arrowUp' serve as alternative jump controls. |
task-17 | 2025-05-12T00:00:00 | moderate | When pressing 'k', the bird can shoot bullets with size 10*10, and the bullets can destroy the enemy. The firing interval of bullets should be at least 0.2s. The data of the bullets stores in 'store.bullets'. Note: Do not forget to implement the new method. |
task-18 | 2025-05-12T00:00:00 | challenging | A boss spawns 10 seconds after the game starts. This boss looks like a normal enemy but is sized 60*60. It spawns at center of the right edge of the screen and only moves randomly up and down on the right side, staying within the screen bounds, without moving left. This boss has 10 lives. The boss will also fire bullets, which need to be distinguished from the player's bullets. The firing interval of the boss's bullets should be the same as that of the player's. A new boss will spawn 10 seconds after the current boss is defeated. Data is stored in 'store.boss', and the boss's bullets are stored in 'store.bossBullets'. Note: Do not forget to implement the new method. |
task-19 | 2025-05-12T00:00:00 | challenging | When the weather is night, a new item type 'Bomb' is provided: it appears as a nuclear symbol. After obtaining it, you have bombs that can be used, maximum is 3. player default has 3 bombs. The current quantity owned is displayed below the health points in the upper right corner. When we pressing 'b' we use one Bomb, it eliminates all enemies, deals one damage to the boss, and clears the boss's bullets. Bomb explosion has a 0.5s animation for the entire canvas, causing the canvas to shake, with the overall canvas superimposing a repeated nuclear symbol pattern. Note: Do not forget to implement the new method. |
task-20 | 2025-05-12T00:00:00 | challenging | Whenever the boss is defeated, the game will enter a special space that lasts for 5 seconds and will reappear after 5 seconds. Inside the special space, it is randomly filled with Coins. After entering the special space, enemies and pipes are removed, leaving only the bird and Coins. The bird's position is in the middle at the bottom of the canvas, and the content of the canvas moves from top to bottom.gains a 3s shield after coming out of space.Data is stored in store.coinPhase. Note: Do not forget to implement the new method. |
