Help on Level Editor (SERIOUS)

[derbon]

Guten Tag, I'm in serious need of a tiled level-editor, and other level-editorsare ether too confusing or crash. SO, i am going to make my own level editor with c++/allegro, and it doesn't go to well. all ive ever goten was a rectangle following your mouse into different cells,

Code: Select all

int x = ((int)mouse_x/tilesize);
int y = ((int)mouse_y/tilesize);

rect(buffer, x, y, tilesize, tilesize, makecol(255,255,255));

thats like all ive done to make it look like a level editor.

so what i really need help with is getting the tiles on da' screen using an array, and scolling, AND saving maps

If you can't think of any way to implement this, I think this might be a bit too complex for you, maybe you should start with something easier. I've only used SDL, but what I did was load a tilesheet, and have an array,

int levelData[SizeX][SizeY];

and it would have a 1 for the first tile in the tilesheet, and whatever tile you want appearing at that specific place. To load, I used fstream, and I parsed through the file for integers, and then loaded them into the leveldata. To display, I just clipped the section of the tilesheet and displayed it at the X,Y coordinates of the levelData * however wide/tall your sprites are.

well, in allegro, im doing somethinglike this:

Code: Select all

if([i]right mouse button down)[/i]
{
map[x][y] = selectedtile;

thats how i get the map to be updated but i dont know how to get the tiles i lay on the screen

Code: Select all

for(int i; i<20; i++)
                {
                        for(int j; j<50; j++)
                        {
                                switch(map[i][j])
                                {
                                                 case 1:
                                                      masked_blit(tset,buffer, 32, 0, j*32, i*32, 32, 32);
                                                      
                                                 case 2:
                                                      masked_blit(tset,buffer, 32*2, 0, j*32, i*32, 32, 32);                                           
                                                 case 3:
                                                      masked_blit(tset,buffer, 32*3, 0, j*32, i*32, 32, 32);
                                                 
                                                 case 4:
                                                      masked_blit(tset,buffer, 32*4, 0, j*32, i*32, 32, 32);
                                                      
                                                 case 5:
                                                      masked_blit(tset,buffer, 32*5, 0, j*32, i*32, 32, 32);
                                }
                        }
                }

masked_blit() will just draws the tile on the screen.

Oh oh, double topic post...

Get the height and width of the tiles, then the width and height of the scroll buffer, then you need to define how many tiles you want in the height and length(usually fits the screen).
post if you got all these

[ibly31]

Why would you ever do all those Cases? Just do:

Code: Select all

masked_blit(tset,buffer, 32*(map[i][j]), 0, j*32, i*32, 32, 32);  

Because the only thing changing in each Case is the number... so just plug it in once and it should work.
and why did you get the tile changing when you click part done before the display? What I did first was have a tile 2D array and then just display it and manually change the numbers and see how it effects whats displaying. Get the basics of a level editor done first before the actually tile changing stuff.

I'm too lazy to explain right now.

But my map editor is open source and you can attempt to read it if you'd like.

Yay! thanks Moosader, I was looking for something like that.
You're my shiny pink knight on a... Moose...

Did you get the new version? If so, *gasp* Moosader made another boo-boo (hardcore memory leak).
