el14moh 0:6b29f9c29a2a 4 My project will be designing a game in which the player must avoid a number
el14moh 0:6b29f9c29a2a 5 of obstacles coming from different locations for as long as possible
el14moh 0:6b29f9c29a2a 6
el14moh 0:6b29f9c29a2a 7 Week 19 Code - Initial test of mbed screen and initilisations
el14moh 0:6b29f9c29a2a 8 Week 20 Code - Add code to move a player controlled ball around the screen
el14moh 0:6b29f9c29a2a 9 Week 21 Code - Add code to generate and move an obstacle down the screen
el14moh 0:6b29f9c29a2a 10
el14moh 0:6b29f9c29a2a 11 Week 22 Code - Significant progress over easter holiday
el14moh 0:6b29f9c29a2a 12 - Diagonal directions added to joystick
el14moh 0:6b29f9c29a2a 13 - Collisions implemented. Game over triggers if character hits a wall
el14moh 0:6b29f9c29a2a 14 - Walls/obstacles developed greatly
el14moh 0:6b29f9c29a2a 15 - Obstacle extended into full wall. Wall structs created and walls travel from all sides of the screen
el14moh 0:6b29f9c29a2a 16 - Walls start of appearing from one side of the screen. As time goes on, more will appear from differnt sides, with multiple walls on screen at once
el14moh 0:6b29f9c29a2a 17 - Cooldown added to walls to ensure a new one will not instantly appear from a side that another wall has just travelled to.
el14moh 0:6b29f9c29a2a 18 - visual warning on screen when walls are about to appear from a new direction
el14moh 0:6b29f9c29a2a 19 - Game now keeps track of score and displays it at the end of the game
el14moh 0:6b29f9c29a2a 20 - Intro screen added
el14moh 0:6b29f9c29a2a 21
el14moh 3:8890b4605a10 22 Week 23 Code - Brief invincibility added by pressing joybutton
el14moh 3:8890b4605a10 23 - invincibilty limit added, indicators added to the side
el14moh 3:8890b4605a10 24 - game loops succesfully
el14moh 7:ca18e8775d8d 25 - Menu added with 4 options
el14moh 7:ca18e8775d8d 26 - DodgeMILD, start the game easy with one wall
el14moh 7:ca18e8775d8d 27 - DodgeMANIA, start the game hard with all four walls
el14moh 7:ca18e8775d8d 28 - Help, get instructions on the game
el14moh 7:ca18e8775d8d 29 - Scores, see the top 3 highscore, will be used for saved scores if SD card is implemented
el14moh 3:8890b4605a10 30
el14moh 3:8890b4605a10 31 NOTES - top wall collision seems to be off
el14moh 7:ca18e8775d8d 32 - horizontal walls still seem to go beyond the left border occasinanly
