Finding And Focusing On Player

When displaying a portion of the map upon the combat screen I had to ensure that the player was displayed on screen at all times.

Finding The Player

In order to find the player within the map I created the “checkTileForPlayer” method which checks if a single integer is one of the various numbers that represent the player.

/**
     * A method that checks for any numbers that represent player-occupied versions of tiles
     * (such as "blank_with_player" and "door_with_player").
     * @param tile The number to be checked.
     * @return A boolean indicating if the tile contains the player character.
     */
    public Boolean checkTileForPlayer(int tile) {
        boolean playerFound = false;
        if(tile == 7 || tile == 104 || tile == 108 || tile == 112 || tile == 116 || tile == 126) {
            playerFound = true;
        }


        return playerFound;
    }

However this still left the issue of going through the unusual layout of my integer array maps.

I solved this issue with the creation of my most ramshackle and unwieldy method “findPlayer”.

This determines the “Column Number”, “Column Depth”, “Row”, “Item Number” and overall “Position” of the players current location.

/**
     * Locates the player within the map and provides their precise coordinates.
     * @return columnAndDepthAndRowAndItemAndPosition An array containing the Column Number,
     * Column Depth, Row, Item Number and overall Position of the players current location.
     */
    public int[] findPlayer() {
        /**
         * An array containing the column number and column depth to be returned.
         *
         * Now also includes which row contains the player along with the exact Item number
         * of the player to pinpoint their exact position with precision.
         */
        int[] columnAndDepthAndRowAndItemAndPosition = {0, 0, 0, 0, 0};

        //int a = 0;
        //^ REPLACED WITH columnAndDepthAndRowAndItemAndPosition[4] !!!!
        int currentRow = 0;

        int columnDepth = 0;
        while (columnAndDepthAndRowAndItemAndPosition[4] < map.length) {
            int currentColumn = 0;
            /**
             * Number Of Columns Loop
             * loops whatever the single column loop would have done several times depending on how many columns there are
             */
            for (int column = 0; column < numberOfColumns; column++) {
                /**

Although this method likely returns more information than is needed it performs it’s intended purpose.

Focusing On The Player

The “setupMap” method does the lions share of the work in actually going through the map and finding numbers representing images to assign to tiles on the combat screen.

As the map is split into nine sections, each big enough to fill the combat screen, the method only displays whichever section currently contains the player.

/**
     * Peruses a section of the map for numbers representing images to assign to tiles.
     * @param targetColumn The column number of the target section of the map.
     * @param targetColumnDepth The column depth (as im using the word "row" for something else) of
