I'm making a Metal Slug remake and need to know how to read a tile map from a ".txt" file. Can you read a document with comma's to differentiate the numbers? I can read the first string but not the whole file. This is the code I have to read from a ".txt" file. It reads the first string in the y direction.


After it reads the ".txt" file, the code then pastes the sprite onto the screen. Whenever I try to read the x value string it says image number illegal.

This is the tile map that I saved to a ".txt" file.

Make sure that your NumTilesY and X are both positive values or being what they are supposed to be. And also, you have to parse the string for commas. Look for a topic on "undocumented commands" or something similar, cos there's some token commands in there.

Out of interest, are you using Pizzamans tutorial?

Ps when I get home , Ill try and paste up a working example of what you need; I'm working on the same thing.

Yup, I'm implementing Pizzaman's tutorial into my game. He did a great job at tile placement but I found a better way to call the collision to make it more into what I'm looking for in a 2d side scroller. Once I get the basics on how to load a tile map from a txt file, I'll make my own tile code. Can't wait to see the code. thanks!

This is what I got on how to load a tile map from a txt file. It only reads the first string though.

assuming you know the width of the map (so we know what to define the array):

this'll get each number separated by a comma. Note that it overwrites the original string of data to keep things simple and quick.


Here's the code mixed with yours:



I suggest you add the map's dimensions to the beginning of the file.

FILE:


so the first thing you read are the 2 lines at the top to define the array.

read string 1, s$
NumOfTilesX = val(s$)
read string 1, s$
NumOfTilesY = val(s$)

Thanks a lot Phaelax. The code looks good for taking out the commas. Right now I get a message that says, "image number is illegal." I'll mess around with the code when I get back tonight. It should be easy to find out whats wrong.

This is the code that works perfect. Thanks again Phaelax!

To fix that, you'll need to place an END after the close file 1

in the middle you see "print s$"
