What I want to do:

I want a small map inside my main map where you see a small overview map about the level. But only areas you have visited before are shown, the rest is black. The mini map must correspond with the main level, because you can use teleport spells to move inside the map and you'll be automatically moved in the level. When saving a game, the info about the "discovered" areas must be saved, too.

I have some ideas to realize this, but all of them are quite very complicated and so I want to ask if somebody has a tricky idea how to solve this topic.

You could make it so, that every wall/floor/object gets visible when the player can see it. Before that they are invisible. Now if the mini-map is a screenshot that refreshes every 10 seconds(or somthing like that) there is only black where the player hasn't been! But then you would have to assign an action to every wall and object... This is the only way that i can think about...

Hope that helped(i dont think it did)

i want to know too ...

Hehe! I want to know as well!

An idea I had though, would be to create a camera in the bottom corner of my screen, with an entity flying over the top (following the mouse).

This wouldn't work with the way you want, though.

Here is a fairly simple bit of code that will display a map on the lower right portion of your screen. The rest would be up to you.

I actually just sent this to Acknex Resource, but instead of making you wait:
Just Call "Map_Window();" in your player action to bring up a mini-map. This is a camera that appears above, looks straight down and follows the player. Then a small view is placed in the lower right of the screen. This is great for outdoor levels. It can also be used for single story indoor levels if all textures facing the camera have their surfaces set to "none". It will also work for multiple stories through a bit of extra coding and level planning.

code:

//========================================

view Map_Cam {} // Create Map camera.

Function Map_Window() //Target camera. Attributes
 {
 Map_Cam.visible = off;  //Show View
 Map_Cam.size_x = 104; //<-- 800x600//128; <--1024x768// Window Size X
 Map_Cam.size_y = 104; //<-- 800x600//120; <--1024x768// Window Size Y
 Map_Cam.pos_x = 663; //<-- 800x600//851; <--1024x768// Window Position X
 Map_Cam.pos_y = 470; //<-- 800x600//614; <--1024x768// Window Position Y
 Map_Cam.tilt = -90; // Look Down
 Map_Cam.pan = 90 ; // Top North
 Map_Cam.Noparticle = On;
 Map_Cam.Audible = Off;

     while(1) // Need Loop so variables update
     {
       Map_Cam.X = my.X; // Follow Players X
       Map_Cam.Y = my.Y; // Follow Players Y
       Map_Cam.Z = 1000; // Use this to Zoom the Map
       WAIT(1); // Need break in loop so code wont choke
     }
}

Here is a screen shot of a kids game I am making for my daughter which shows the map code in action:



Although not exactly what you want, I hope that it helps a little.

If you´re using braxt techniques with an overhead camera u can cover your level with a grid of sprites for example, like a "roof". Then you simply kill the roof pieces when the player is coming near.

Hi Braxt, it's a very beautiful screenshot.

lookk this :

Thanks Alain! I am happy that you felt it was worthy of example.

Very clever, Alain. I love simple solutions!

Thank you Braxt, a very wonderful example...
