Hi Mandaw.
You could go about thinking how to get started to build this game by following the example that I run through below.
To initialize players that leave a trail in a Tron-like game, first you have to define the players' starting positions by choosing coordinates on the game grid.
Then, set initial player directions and assign a starting direction (up, down, left, or right for simplicity) for each player.
The next step is to create data structures for player trails. For each player, initialize a data structure (for example a cell array or a matrix) to store the coordinates of the trail. Add the player's starting position to this data structure.
Then, draw initial player positions on the game area using different colors for each player.
As the game progresses, update the player positions and their respective trail data structures with each movement. The updated trail information will be used to render the trails on the game area and to detect collisions between the players and their trails.
The following is an example code that initializes a Tron-like game with a 100x100 grid with two players. This is just a starting point and you can build on top of it.
% Initialize game parameters
gridSize = 100;
numPlayers = 2;
playerColors = {'blue', 'red'};
% Define player starting positions and initial directions
playerPositions = [50, 25; 50, 75]; % positions are correspondingly x1, y1, x2 & y2
playerDirections = [0, 1; 0, -1]; % directions of movement correspondingly are dx1, dy1, dx2 & dy2.
% Create data structures for player trails
playerTrails = cell(numPlayers, 1);
for i = 1:numPlayers
playerTrails{i} = playerPositions(i, :);
end
% Create game area
figure
axis([1, gridSize, 1, gridSize])
grid on
hold on
% Draw initial player positions
for i = 1:numPlayers
plot(playerPositions(i, 1), playerPositions(i, 2), 's', 'Color', playerColors{i}, 'MarkerFaceColor', playerColors{i})
end
