What?
           A map editor for Cptn. Ruby.

Why?
          Because.

No, seriously, why?
          Because I needed to have a starting project.

Current version?
          Version 1.0

Screenshots?
Sure:


Should we credit you if we use this?
Yeah! It's not much, but I've made this script; and no-one should get credit where it's not due..
So, just credit me, AmIMeYet, if you use this..

Requirements?
Ruby
Gosu
The Cptn. Ruby example (comes with gosu, in the 'example' directory)

How do I install it?
Put the script inside the folder you've got the Cptn. Ruby example in, and run it.

How do I use it?
Use buttons 1-4 to select the Earth, Grass, Gem and Erase tiles.
The current selection will be placed in the title bar, along with the tile currently hovering over.
Click with the left mouse button to apply the currently selected tile to the map.
Press S to save, and overwrite the default map file (so back that one up!)

Any bugs?
If you launch the editor, and then go do something else on your computer, it crashes.. so always SAVE.

And the code?

Hey AmiMeYet

Great work with the map editor for Cptn Ruby

though when I ran it the sprites(gems) where not placed where they should have been
they where a bit lower than where they should have been (compared to where they are when you play Cptn Ruby)

so I edited the source code and now it works fine(for me at lease)

please try out the changes Ive made and see what you think

I plan to use the new version of your map editor for my game Arthur's Adventures,hope you don't mind,I will give you full credit of course

Here is the source code for the new version I made

=begin

I'd be honored!

Though, I'm afraid I can't test your source.. I don't have blueshield's and gold. .. ..  Have you posted the right version? (as Gold should be Gems for cpt. Ruby)

Also, I'm working on a game of my own (a small, simple thing to show my teacher I'm already familliar with OO-programming, so I don't have to use some dumb point-and-click game program), and I'm thinking about making a small editor thingy on the side..
So I'm thinking on improving it too... making it more user-friendly, etc.
Like pressing UI-buttons in the editor, instead of pressing 1,2,3 and 4 on your keyboard.

Hey AmiMeYet

whats your email address ,ill send you the other files u need if you want,like blueshield.png and gold.png

or you can make a copy of original gem file and rename it to blueshield.png same goes for gold.png

as far as gems not being in the source code any more,its because I am using gold now in place of gems so I though it would be best to rename it in the code too

run your map editor(v1.0) look at where the gems are placed that are the position above ground or grass tiles,the gem is partly inside the ground or grass tile,that how it appears for me any way

Talk to you soon
Shinobi Chef

Hey AmiMeYet
Your idea of using UI buttons in an improved version of your editor sounds great

Would you like to make a similar version of your editor but for my game "Arthur's Adventures"?
as they are almost the same except my game will have more tiles and objects that you can place

What is this game you are working on? what type of game is it?

Bye for now
Shinobi Chef

Merely a small and simple rpg (without the roleplay part :p) thingy..
But all there is is 1 or 2 players, a map built of '#'s and other characters saying stuff.
It's really low-tech.

Also.. I haven't even started on the map editor!
I'm a little too busy with the game right now.

Also, about the email.. I hate spam.. so I'll give you one of my spam-accounts.. (security layer #1).
It's in the attachment (security layer #2)

Edit: Do you have msn? If so, mail your msn address to me.
