  1. Ah, that is unfortunate Guess I'll have to change my game idea a bit So anyway, thanks for your replay
  2. Hello Forum [img]http://public.gamedev.net//public/style_emoticons/default/smile.png[/img] I started working on programming a small 2D platformer with the SDL and had a strange bug in a specific method. What this method does is first checking for the arrow keys wether they are pressed or not, then for the WASD keys. Three states are currently used: The Left/Right keys move the Player two the specified direction. The combination of the Up-key and the S-key let the Player Jump. The problem I have now is that the player can't jump and move left at the same time, but he can actually move to the right while jumping. I've done some testing and found that my program doesn't register the left key while the Up-Key and the S-key are pressed. The relevant code: [CODE] void CPlayer::ProcessMovement () { if (g_pFramework->KeyDown(SDLK_UP)) { if (g_pFramework->KeyDown(SDLK_w)) { cout << "Direction: 1, Action: 1" << endl; } if (g_pFramework->KeyDown(SDLK_d)) { cout << "Direction: 1, Action: 2" << endl; } if (g_pFramework->KeyDown(SDLK_s)) //The section for triggering the jump method { cout << "Direction: 1, Action: 3" << endl; if (m_bJumpAllow == 1) { cout << "Jump" << endl; Jump (); } m_bKeyPressed = true; } if (g_pFramework->KeyDown(SDLK_a)) { cout << "Direction: 1, Action: 4" << endl; } } if (g_pFramework->KeyDown(SDLK_LEFT)) { if (g_pFramework->KeyDown(SDLK_w)) { } if (g_pFramework->KeyDown(SDLK_d)) { cout << "Direction: 4, Action: 2" << endl; } if (g_pFramework->KeyDown(SDLK_s)) { cout << "Direction: 4, Action: 3" << endl; } if (g_pFramework->KeyDown(SDLK_a)) { cout << "Direction: 4, Action: 4" << endl; } } if (g_pFramework->KeyDown(SDLK_RIGHT)) { if (g_pFramework->KeyDown(SDLK_w)) { cout << "Direction: 2, Action: 1" << endl; } if (g_pFramework->KeyDown(SDLK_d)) { cout << "Direction: 2, Action: 2" << endl; } if (g_pFramework->KeyDown(SDLK_s)) { cout << "Direction: 2, Action: 3" << endl; } if (g_pFramework->KeyDown(SDLK_a)) { cout << "Direction: 2, Action: 4" << endl; } } if (g_pFramework->KeyDown(SDLK_LEFT)) //Checking for movement to the left Run (0); if (g_pFramework->KeyDown(SDLK_RIGHT)) //Same as above for the right Run (1); if (!(g_pFramework->KeyDown(SDLK_LEFT)) && !(g_pFramework->KeyDown(SDLK_RIGHT))) CancelRun (); //This method Stops all horizontal movement if neither left or right is pressed if (g_pFramework->KeyDown(SDLK_DOWN)) { if (g_pFramework->KeyDown(SDLK_w)) { cout << "Direction: 3, Action: 1" << endl; } if (g_pFramework->KeyDown(SDLK_d)) { cout << "Direction: 3, Action: 2" << endl; } if (g_pFramework->KeyDown(SDLK_s)) { cout << "Direction: 3, Action: 3" << endl; } if (g_pFramework->KeyDown(SDLK_a)) { cout << "Direction: 3, Action: 4" << endl; } } CheckJump (); if (m_bKeyPressed == false) { CancelJump(); } else { m_bKeyPressed = false; } }/ [/CODE] I hope you can help me with this problem, thanks in advance for that [img]http://public.gamedev.net//public/style_emoticons/default/smile.png[/img]
