c – 游戏跳跃逻辑

以下功能用于在按下特定键时更新玩家的位置.允许玩家左右移动,并跳到同一个地方,或者向左或向右跳(形成弧形).

bool updatePlayerPosition(Movement* mov){
        if (this->keyPressed(SDLK_RIGHT)) {
            mov->applyForce(1); // Changes the veLocity in X
        }   
        if (this->keyPressed(SDLK_LEFT)) {
            mov->applyForce(-1);  // Changes the veLocity in X
        }           
        if (this->keyPressed(SDLK_SPACE)) {
            mov->jump();        // Changes the veLocity in Y
        }       
        if (this->keyPressed(SDLK_DOWN)) {
            mov->fallDown();   // Changes the veLocity in X and Y
        }

        Point* pos = mov->getPosition();

        // check whether the position is out of bounds
        if(Level::allowsMove(pos)){
              // If it is not,I update the player's current position
              position->x = pos->x;
              position->y = pos->y;
              return true;
        }
        // If the movement is not allowed,I don't change the position
        else {
              mov->setPosition(*position);
              return false;
        }
    }@H_616_10@ 
 
这是一个错误：当我到达关卡的末端(有一个固定的宽度)时,如果我试图向右移动并同时跳跃,则玩家会跳起并停留在空中.只有当我释放空格键时,玩家才会到达地面.
 
 
我怎样才能解决这个问题？
