MATLAB: How to reference when an image touches another

gameimages

I am essentially creating a game within MATLAB. Currently I am having an issue with causing something to happen if two objects touch.

An example of how the world is set up is a 10×10 cell named World.

so if World{x, y} = Player; World{5, 5} = Monster;

How would I be able to decrease Health by 1 if the player touches the monster? A simple Player == Monster doesn't work and I need advice.

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.

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'
