MATLAB: How to make multiple variables equal a class

class-based

Hello!

I need some help with trying to make multiple variables equal a 'class.'

I started using MatLab 2-3 months ago, so I am not very good at it.

I am currently making a menu-based RPG game, and I need to make an "equipped" screen.

What I am having trouble is making multiple variables = 1 "class"

For example…

Swords = (Bronze sword, Steel sword, Diamond Sword)

Helmet = (Bronze Helmet, Iron helmet, dark helmet)

Leggings = (Bronze Leggings, Iron Leggings, Stone Leggings)

and so on.

This way, I can prevent users from equipping a sword into a helmet slot, or prevent a legging item from equipping to a weapon slot.

I apologize if this is confusing.

Thank you so much! I will attach a copy of the game for assistance, or if you would like to play it.

Try the following testGame.m to see how to use object-oriented programming in Matlab. You'll need to define classes via classdef function. This link is helpful too: https://www.mathworks.com/help/matlab/matlab_oop/create-a-simple-class.html

Since most avatars have 2 hands, you'll need a separate function to decide what to do when you try to equip more items than the avatar can handle. Ex: equipping 2-hand sword + 1-hand shield shouldn't be allowed. You'll have to unequip the other hand, etc. This, I leave up the the game developer.

%testGame.m
P1 = Player('player1'); %Create new player of lv1 named player1
NewItem = Weapon('Sword Of Matlab', 10000, '2-hand'); %Make new item

P1.wear(NewItem); %Equip player with new item

NewItem = Armor('Shield of Functions', 10000, '1-hand'); %Make new item
P1.wear(NewItem); %Equip player with new item
P1.levelUp %Level up the player
P1.Level  
%   2
P1.Armor
%   Armor with properties:
%        Name: 'Shield of Functions'
%     ArmorPt: 10000
%        Type: '1-hand'
P1.Weapon
%   Weapon with properties:
%       Name: 'Sword Of Matlab'
%     Damage: 10000
%       Type: '2-hand'

MATLAB: How to reference when an image touches another

You can save the positions of the player and the monster in separate position vectors (then you can use sqrt((x_p-x_m)^2+(y_p-y_m)^2) to calculate the distance). This would support non-integer locations.

You could also use binary matrices for location, which would enable you to check for a collision with any(monster_loc & player_loc). This method supports multiple monsters.

Which of these is the best approach depends on what the rest of you program does/needs.

still_in_game = true(1, number_of_players);
while any(still_in_game)
    for player_number = find(still_in_game)
      %if dice rolls number that was chosen by player, they're knocked out,
      %otherwise can continue playing
      if dice == chosen_num(player_number)
        %HOW TO SEPERATE PLAYER NUMBERS IN COMMAND WINDOW (PLAYER 1, PLAYER 2,
        %PLAYER 3?
        fprintf(' Player %.0f youre knocked out.\n', player_number);
        still_in_game(player_number) = false;
      end
    end
    for player_number = find(still_in_game)
      fprintf('Player %.0f Youre still in.\n', player_number);
    end
end
