Random World Generation

WorldLover

As I said in the post "How do MiniMicro tiles work", I'm planning to make a survival, Terraria-like game. And i realized that tiles would be the best way to create a random pixel world. So I made the tiles set, and made a function that creates a random 100x16 chunk. I'm still making the functions that will set the environments like caves, rivers and dugeons, but I will tell about it later, when I finish it. The process i used to create a random chunk consists in the following steps:

The program sets two variable that defines the y and x position in which the next block will be placed, and also a third variable that changes to a random number every time and will define what kind of block will be placed.
The program checks the depth of the layer he's creating, and depending on it, there will be just rock and ores, or rock and dirt, or just dirt. If the layer is very deep, the program will place rock and ores. If the layer is near the surface, there will be just dirt and, rarely, a rock. If the layer is the surface, there will be just grass, flowers, mushrooms... this kind of things.
This part of the code is still not done, but i will do this when i finish the script that builds the caves and etc. The program will check again all the blocks, always having a little chance of setting a cave or dugeon there (if the layer is deep enough), or even a house or river (if the layer is in the surface).

As you can see, the code is not so complicated.

Here's the code. Of course, if you want to use it you will have to adapt it to your game. And note that there's a dictionary that assign the names of the blocks to their position in the tile set. If do you want to test the script and the tile set, make a folder with any name you want, save there a "fileName.ms" archive with the code i'm posting, and put the tile set there also, with the name "terraTile.png".

...And here's the tile set:

If you want to see the random chunk, you will have to download the tile set, copy the code, and create a new folder. Then save a ".ms" file with the code above, and put the tiles set inside this new folder. If it don't work, please tell me and i will try to find out what's going wrong.

Very cool! Can you post a screenshot of what the result looks like?

WorldLover

Of course!
Here is a screenshot of the surface...

...and here's a screenshot of a deeper layer.

Beautiful! This looks like a lot of fun. 🙂

I've made some little updates in the random world generator project. Now, it creates underground lava, water and acid pools,and it's possible to break the blocks (though they break instantly, don't drop and it's not possible to place them yet).

WorldLover

Here's a screenshot of a whole chunk:

The system i used to create this random pool can be resumed in the following steps:

The program creates a variable, "ypos", that is set to the height of the chunk. And creates another variable, "xpos",, that is set to a random number between 0 and 4. This will be the X position in the tiles where the water/lava/acid pool with begin.
The program creates two more variables, that will define the size (width and height) of the pool. The "length" variable i set to a random number, from the number of the tile where the pool will begin to this same number more 11. This is the step in which the pools take random forms. Without this step, the pools would be just water square.
The program go into a loop that remains until the "ypos" variable reaches the number 1. In every loop, the "ypos" variable is set to itself minus one, and the program sets another variable (build) is set to a random number between 0 and 30.
The program checks the "build" variable, and if it's zero, sets a lava pool. If it's 1, a water pool is placed. And if it's 3, a acid pool will appear. Note that, if instead of setting the build variable to a random number from 0 to 30, i had set it to a random number from 0 to 50, the pools would be more rare. The bigger the number, the rarer the building
Whenever the program sets a pool, it subtracts 7 from the "ypos" variable. This avoids overlapping.

And, with this simple steps, the pools are created in random places,with random forms and sizes, without overlapping or oversizing.

I've made a function to build caves and i finished the function to build the dugeons. Here is a screenshot of a 100x100 world with random generated underground pools, caves and a dugeon:

I've made two kinds of caves: one of them is bumpy, and the other also have some holes, but it's on the roof. That big square cavern with a dugeon has a bumpy floor, and that little cavern near the bottom right corner has a bumpy roof.
The movement of the water and lava is still not done, and i still don't know exactly how i will do this. For now, i'm working at the buildings.

P.S. I will decrease the ores generation later.

Looking good.

WorldLover

SynapticBytes Thanks!

I've made some progress in the Random World Generator project (which i'm calling Terra), with the help of Joe Strout. Now the player can move and detect walls and the floor. If there's a wall, he stop walking. If there's not floor, he falls.
Here's a screenshot:

jstrout

Looking great! What fun! 😃

I've made some progress. Now the game knows the time the blocks takes to break, with the respective tools, using a spreadsheet and the "tsv" library, made by Joe Strout. And there's a simple animation to when the player is breaking some block. But there's still no cracks.
Here's a screenshot.

The player is breaking a dirt block. But we can't see it yet, since i still didn't code the cracks.

WorldLover

The cracks are done! It working perfectly!

Now i can concentrate in other things, like the movement of the player and the buildings.

jstrout

Looking really good!

I've made some progress. The player's collision detection is now very better (though it's not perfect), and i'm working on the mobs. I've made the zombie, the medium slime (the big and the small is still not done), and a different mob that i called Flo Eye. The pixelart of the eye and the slime is not mine. They're from Stephen "Redshrike" Challener, hosted by OpenGameArt.org. Here's a screenshot:

Also, now there's now kinds of trees:
1.The purple flower tree

2.The lemon tree

3.The apple tree

4.Almost the same of the normal tree, but the form of the leafs is a bit different

5.The normal tree

I'm still embedding the mobs and their behavior.

WorldLover

I'm slowly making progress. I've made a function to show the items in the inventory, but it runs a bit slowly, so i still have to improve it somehow. But at least it hows the items. For now, still working on the mobs and NPCs. I've made two; the Builder and the Warlock. They are still starting to start... the only they do is walk around, and they still don't have collision detection, nor the mobs. It's also going slowly because i'm working on another project. A MiniScript image editor. Maybe i will create another thread about that, but it is still starting to start.

Here we have a screenshot of the two NPC's i started to make. The zombie is not going to attack the player... he still has not collision detection of player detection. I think i will work on the detection now.

that looks really cool! I hope I can make a game like that someday.
