I am going to be taking on remaking the original NES LoZ in java, and I shall post progress on here as I go, but I felt like making a topic for this.


So first thing is first, I need to learn how I can make maps using tilemap images.



That is the tilemap image, and I am guessing the best way to go about an actual map is with a 2D array, but what I can't figure out (even looking online and a lot of googling) is how I can use that image for a map.

I haven't the first clue, but goodluck getting this project going!

Each image tile has an index, and based on that index you crop the map image to get the tile. Or, when you first load the game, chop up the tilemap into an array of smaller images, and index into that array to get a tile.

Did you take a look at the example code from my Java RPGKit which I gave you on IRC a few days ago?

I did, but I honestly couldn't get it all figured out, along with that, I couldn't even get Eclipse to work with it. :/

Can you ask more specific questions about what you couldn't understand? And what you couldn't get to work in Eclipse?

You should figure it out or ask specific questions instead of asking us to give you the same code again. Start by reading the main method of the CeltQuest demo.


You shouldn't bother with Eclipse until you practice setting the compiler flags by hand, because you won't understand what Eclipse thinks is going wrong until you've had the same thing go wrong yourself.

I think we should resurrect that thread about asking questions the intelligent way to append a "be specific" section, although now that I'm writing this, I am thinking we might already have that. Anywho, specifics! Let's have 'em.

I shall look into the main method and see what I get from that then.



I have been using eclipse since I started, I will run it again and see what the console part says and post it.

In general that's the best place to start in dissecting any program.


If you aren't familiar with the command line arguments to java and javac, you should still set some up by hand.

Code:


Any idea what is going on here? This is the issue I have had that I mentioned earlier. :/

Code:
is a pretty good indicator. It can't find a file, based on:

Code:

I'd say it's data\map.cqm. Does that file exist?

I assumed it couldn't find the file, the source didn't have it, and I believe that file is generated in the running of the code to make a map. I am not sure though, just a guess from the code and seeing this:


Code:


I also get an error with this message for the following code:


Code:



Code:



Edit: Found the map.cqm, I am going to try to re-direct the location to where it is at, as I think it is set up slightly differently since I did it and not elfprince.

Sorry I missed you on IRC.


This looks like an error writing the file. I suspect that your working directory is messed up by Eclipse (and or the data directory is missing).


This is related. Since the map wasn't created, it couldn't be read.

File paths are the pickiest things on the whole planet, besides maybe a worker in the fashion industry. Make sure that the path you're working with both is a valid one, AND when you do something like "data/map.dib" it applies to a folder "data" not in the path of the source, but of the compiled file. Most Java IDEs (well at least netbeans) will copy everything over from a project folder to a distribution folder, so that might not be the exact issue. If nothing else, try to clean up your path a bit and remove all garbage, keep things all in one organized place, and try rebuilding. Before you do that though, post the layout of the built project's class path, so we can see if it's set up correctly.
