I am making a level editor that needs to be able to read and write letters and numbers from a .lvl file (this is just a text file with .lvl instead of .txt). The level code looks somthing like this:

1111111
1033301
1010101
11ABC11
1200021
120D021
1111111

I need to read each letter/number from left to right, top to bottom, one by one. I also need to write the same way. I would like to be able to read/write specific x/y of the level code grid, aka change the 0 on the second row to an E on command. Can someone help me with this?

I am sleepy ATM but maybe someone will help you. If not it will be another 24hours before I can look at it again. I can tell you a couple of things I would do.

As far as reading left to right, top to bottom: you can just use read string command to get each line and then use the mid$ command to extract each character.

The writing to a specific location in the file is a bit trickier. If you know the xact contents of the file already then you can use the skip bytes command to skip to that loaction in the file and change it. Otherwise get ready to learn some memblock programming and use meak memblock from file. It will then be easier and faster to read and write data.

I was thinking, would it be easier to load and save a arrays to/from files? I don't know much about arrays, but I am now reading the manual to try to figure it out.

Ok, I've started testing arrays, and I found out that they save them encrypted. This is a problem because I need to be able to get into the files and change the arrays as needed. Oh, and my levels are going to be 40x25 each, so maybe arrays aren't the best answer.

Teehee, I was just making a map-maker program (DBP).

Feel free to use it. Right now, you can make maps (ofcourse), resize, load, choose between 9 tiles and 2 tools.

Hey, that's an idea! Adding characters as tiles... Thx

Sven B.

This is really a nice level editor but I think it would do better if you could use your own custom colors instead of the preset ones and if you could import your own square textures.

Just do something like this after the user enters in a file to use.



That way the textures would always be square.

Dunno about Pro, but arraysin Classic will save encrypted as long as they are not string arrays.

Yes, I had that request of using sprites as tiles. But, since you can zoom out until each grid square is 1px heigh and width, this would be very unhandy. The option to choose your own color values is a nice idea though, and thus I will work on it.

Here's an updatet version of map-maker with more features:
