Yet another RPG Engine.

Hmm, this is the third one so far isn't it.
So far I've got it so you can move around, you can change maps by walking off the side of one (Which map leads to which is defined in a file). I'm going to add a piece of code soon so that you can't walk on things like tiles etc.
The code is currently quite messy and needs to be cleaned up I know.
And I might start working on the Map Maker soon.

}Edit: Changed the way it loads the maps and changed it so you can't walk on walls anymore.

Good job :)

This reminds me of a sort of program I fiddled with back in the day (in QBasic no less!). You had to reach the goal, but there were hazards in the way.

For example, to swim across the river you had to find the goggles / snorkel first and so on.

I wish I had that code...

Chip's Challenge much, Walrii?

[Snif]

Now for some BATTLES! Good job Neo.

[Insane2757]

Chip's Challenge much, Walrii?

YES. Very yes.

[neozf]

Lol, Snif: For how Imma just finish getting the basics done, maybe add a few more tiles, then try working on the battle part of it :p

For some reason my Map Maker won't save files, yet the test I made which uses the exact same code works.
The problem is in the saveMap function.

[Dazed_n_Confused]

Did you forget to put saveMap(mapNumber); back in?
Also, you realise that isn't saving whatever map you build right? It saves an all grass map.
I'm assuming this was just leftovers from debugging and you know about that, but I don't see anything else that would make it not work. How did you run your test class?

At any rate, you should probably use 'else if' for that block of 'if' statements in the mouseDown event.

[neozf]

Yea I realise I haven't put saveMap(mapNumber); back in and that it saves an all grass map, that was to create the exact same thing it did in the test since it worked there...
For the test class I just created an object of it, then ran mapMake() and it saves completely fine.

[Walrii]

I looked at it... and it looks like it should work :(

Maybe though, if you're running the applet within a web browser (or maybe an applet launcher) Java won't give it read/write permissions to files. Though, if you run it from the command line, then it probably will be given read/write permissions.

That's my only thought.

[neozf]

Maybe... I even tried having it use another class to save the file :/

[Sim9]

An exception may be generated in the catch(Exception e){} code which could give more insight into the problem :)
