Hey guys/girls, I am working on a game called Jump Pacman and would like to see if it works on your systems as my current system is a bit old and it lags a little. http://files.desmondtaylor.co.uk/jump_pacman.zip Could you please test this and let me know about any lagging or flickering along with your specification so that I can work on it. Any advice is also welcome. Here is a screenshot: |

That looks bonny (though the two platforms look like they spoil the menu a bit), do you have any more screenshots (like in-game action)? Neil. wii:0356-1384-6687-2022, kart:3308-4806-6002. XBOX:chucklepie |

No lag whatsoever in the main menu, but the game doesn't work when pressing "Play game"(options screen doesn't even open). The screen is cleared, the pacman stays in the position he was when pressing enter and in the top-left corner is a platform. Nothing moves and ESC returns to the main menu. pc specs: 2.5GHz dual-core processor, video card:GeForce 7050 / nForce 610i " There are plenty of wonderful ideas in The Bible, but God isn't one of them." - Derezo |

Yea I noticed he speeds up. I haven't done the rest of the game yet as I only started making it yesterday getting practice in for SpeedHack This game is that hacked together that its all in main.cpp Edit: The code. 1#include <allegro5/allegro.h>

Since you wrapped everything up in a if(game.ticked) statement, I don't see why this happens at first glance... Somebody better at coding than me should be able to resolve your problem. " There are plenty of wonderful ideas in The Bible, but God isn't one of them." - Derezo |

Yea, I only built it like this so it's quick for me to edit but since it's so messy and I'm trying to complete it in a 3 day period since that's how the SpeedHack goes. If I was to make a game properly I would use classes and have everything handled correctly. But yea, I can't seem to fix the problem when you keep your finger on a button making the player move faster :/ It also does the same moving the mouse Edit: I have fixed the player speeding up issue. The fix is below. 1void update_events()
2{
3 if ( al_get_next_event( game.queue, &game.event ) )
4 {
5 switch ( game.event.type )
6 {
7 case ALLEGRO_EVENT_DISPLAY_CLOSE:
8 game.quit = true;
9 break;
10
11 case ALLEGRO_EVENT_TIMER:
12 game.ticked= true;
13 break;
14
15 case ALLEGRO_EVENT_KEY_DOWN:
16 keys[ game.event.keyboard.keycode ] = true;
17 break;
18
19 case ALLEGRO_EVENT_KEY_UP:
20 keys[ game.event.keyboard.keycode ] = false;
21 break;
22 }
23 }
24}
Edit 2: The code is now that messed up I am going to have to write it properly like I normally would with making a game. I am going to work on that tomorrow but make some notes before I go to bed. Edit 3: I have updated the executable that can be downloaded from my file depot. Link in first post. |
