My first map editor and map loader!

[mv2112]

It's amazing what you can do when you put your mind to it . I just made a simple map editor, it only has 3 tiles right now and it outputs to a text file when you press the s key.
The map loader translates the text file and loads the map with the tile sheet. My code is messy and it has some memory leaks but its because i was experimenting, anyways here it is!

Map Editor:
Main.cpp:
Keys 1,2 and 3 switch tiles, p erases all ,left click to place a tile and s saves to map.txt

Code: Select all

#define USE_CONSOLE
#include <allegro.h>
#include <iostream>
#include <vector>
#include <fstream>

using namespace std;

int main()
{
	int x;
	int y;
	int pos;
	int w;
	int h;
	int filex=0;
	int filey=0;
	string title="tile_sheet.bmp";
	allegro_init();
	install_keyboard();
	install_mouse();

	BITMAP* buffer=create_bitmap(640,480);
	BITMAP* tile;
	tile=load_bitmap(title.c_str(),NULL);
	clear_to_color(buffer,makecol(0,0,0));
	show_mouse(screen);
	char xout[100];
	char yout[100];
	while(!key[KEY_ESC])
	{
		xs=xx.size();
		ys=yy.size();
		itoa(xs,xout,10);
		itoa(ys,yout,10);

		clear(buffer);
		pos=mouse_pos;
		poll_mouse();

	    y=(25-(pos & 0x0000ffff))*-1;
	    w=x+50;

Here is the tile sheet that has to be in the directories of the map file and the 2 executables


EDIT:
O ya, if you compile, you will probably need the allegro dll, im not sure which one of the 3 it is lol. Here is a link to all of em http://home.roadrunner.com/~mvonline/

Nice! I remember when I made the first level editor for the RPG I was making. It just feels so cool once the level is up and running in the engine without any text file altering from you. Good job!

[GroundUpEngine]

+1 for Good Job! Editor's Rule! :P

[mv2112]

I added in a sprite system that loads a sprite from a config file (sprite.txt) and includes a collision system with the map and obviously movement, also added in support for special tiles you can walk through in the map editor.
Now all i need to do is make a program to create the sprite config files.

Pretty cool dude, keep up the good work!

[MrDeathNote]

Well done man, keep it up.
