You must create asmall 2D game where a dolphin escapes earth after eating some fish. Orany hero collects any valuables before leaving the place.

You will use 2d view (top-down or profile). You gonna learn how to use of minilibx (graphical library).

I implemented basic game mechanics that you can find on traditionnal games.

I added a story extension if you use a specific map size. You can discover it by playing onmap/piano.ber :

In this project, I decided to use a 2.5d isometric view.
In order to create the isometric effect, here are the steps :

• Step 1: I parse my map to get all my elements into a 2 dimensional array of char (char **)

111111111110000000011000000001100000000110000000011111111111

• Step 2: From last line, I moving up in my array, and for each line I am moving up, I am gonna add one more X at the begining of my line. This has for effect to create my 45 angle view. I finish by completing each of my line with X's in order to get a squared map that will perfectly fit inside my window.

XXXXX1111111111XXXX1000000001XXXX1000000001XXXX1000000001XXXX1000000001XXXX1111111111XXXXX

• Step 3: I use this new 2d_map to print my textures at the right place.

.xpm format does not support transparency. If you are doing a 2d top-view(for example), you can counter this problem by pasting your texture on top of your floor texture. But because of the perspective, I couldn't use this method, so I recode the mlx_put_image_to_window from the minilibx, mlx_pixel_put(), to make it more efficient and faster, to have a really smooth result.

voidmy_mlx_pixel_put(t_test*test,intx,inty,intcolor){char*dest;dest=test->data.addr+ (y*test->data.line_length+x* (test->data.bits_per_pixel /8));*(unsignedint*)dest=color;}

Then I simply told my algorithm that if it encounters a specific dark pixel (0xFF000000), It does not need to print it.

I managed to generate differents furnitures, depending on how the walls are placed inside the map playable zone.

I also managed to display differents collectibles with pseudo-randomizer algorithm. (Because randomness does'nt really exist)
