Creating similar game to google dinosaur game

Hi, I was looking for some help to figure out how to stop my gaming function when the moving object hits the obstacle, like in the google dinosaur function and to show a running score on my figure for the high score. Anyone know some helpful tips to code this?

How are you representing your moving object, and how are you representing the obstacles? Is movement at a constant speed (though potentially different directions?) Are all distances involved multiples of the constant speed, or is it necessary to interpolate the fact of having hit?

So here is my code for making the objects move. My variable square only moves up and down since that is the object that is jumping. My variable square2 is moving backwards from the right of the screen to the left for my other square to jump over and my background is moving to make my first square appear as if it is moving forward too. I will bold the part of my code that deals with the two squares hitting each other.

function game_step(~,~)

        background_img = [background_img(:,11:1270,:) background_img(:,1:10,:)];
        Background(:, 101:740, :) = background_img(:, 1:640, :);
        Background(527:606, 761-Countcol:840-Countcol,:) = square2;

        if trigger == true && Down == false

            Countrow = Countrow + 10;
            if Countrow == 150
                Down = true;
            end

            Background(529-Countrow:608-Countrow , 121:200, :) = square;

        elseif trigger == true && Down == true

            Countrow = Countrow - 10;
            if Countrow == 0
                Down = false;
                trigger = false;
            end

            Background(529-Countrow:608-Countrow , 121:200, :) = square;
        else
            Background(529:608, 121:200, :) = square;
        end

        imshow(uint8(Background(:, 101:740,:)));
        Countcol = Countcol + 20;

        if Countcol == 760
            Countcol = 0;
        end
        gamescore = gamescore + 20; 
        *if ((Countrow <80) & (any(Background(400:640,101:180,:)==0)))
           closeFunc();* 
           name = input('What is your name?: ');
           highscore = xlsread('Highscores.xlsx');

        end
    end

I guess it didn't bold so here is the code I am talking about:

if ((Countrow <80) & (any(Background(400:640,101:180,:)==0)))
           closeFunc();

so it definitely works to some extent, but the square2 has to hit the square entirely or when the square is jumping, if it hits the square2 in the middle, then it will think it hit. However, if the square hits the square2 on the edge, but definitely still hits it, the code will not pick it up as a hit

[Walter Roberson]

Remember, the above code is the same as

if all(all((Countrow <80) & (any(Background(400:640,101:180,:)==0,1)),2),3)
         closeFunc();

The fragment

any(Background(400:640,101:180,:)==0)

only applies the any() to the first non-scalar dimension, leaving you with a 1 x 80 x something array that the default all() rules apply to

Okay, great thank you! It still doesn't end the game if it hits the corners of the sqaure for some reason. Also, do you have any suggestions for displaying a game score on the figure?
