HI dear author,
It's truly a honor to write a letter to you, I'm building your project nowadays and found the error when building as following, I wonder if there is a chance that you know the reason? :)

thank you
best regards to you

Whenever the user presses 'W', 'A', 'D', 'S' we should allow them to move around.

Steps

0. Spawn player at designated spawn point in map data
1. Allow the player to walk around the scene without going out of bounds

I need the ability to render a minimap on screen so that we can track the player location and ensure that rotations / movement is working. We can split this into the following discrete steps:

• Storing each map in an external text file
• Reading the file into a 2D structure
• Generate a bitmap using the 2D array
• Display bitmap onscreen
• Display player position on minimap

Generating The Bitmap

Each block in the map is a wall. We consider each wall unit to be at least 1 meter long. Let's ignore
resolution independence and implement the simple solution.

1. Create a (numRows * blockSize) x (numCols * blockSize) RGBA 2D matrix
2. For each tile in the map, draw a blockSize * blockSize color coded block in the image.

The player should be able to walk around a 2D world and have the game track the player position. Things we need:

• Some way of rendering the minimap
• Detecting player movements
