RE: How create a new Point in the Minimap
something similar to:
Dist(pos_2d, map_center) < MapRadius

Maybe you can post you're solution as well... there are more people that can make use of it... after all this community that shares their ideas and skills with each other.

There is always evil somewhere, you just have to look for it properly.

hi, you can use drawRotate preceeded by D.clip (this will allow you to draw rotated images in rectangular mini map preview)
but you can't mix rotate with masking (circular mini map)

RE: How create a new Point in the Minimap
I was looking for a solution for this too. The hints were not exactly clear to me though. (Perhaps I should have taken math classes in school :-)

I came up with the following code. I don't assume it's the best method to do this, but at least I could make it work this way. The peer dot calculation is in the second part of the draw function. After that, an arrow is also drawn in the center to see which way the player is looking. rect is the rectangle used to display the minimap on screen. mapDot is a little image that is loaded for every peer. In my game, every player has his own color, so you could leave out the part of coloring the dot if you want to.

PHP Code:
void cMiniMap::draw(EE::Vec2 &pos) {
    if (!
guiLoadedloadGui();
    if (
hidden) return;


    if ((*
minusButton)()) {
        
radius *= Time.d();
        if (
radius 150radius 150;
    }
    if ((*
plusButton)()) {
        
radius /= Time.d();
        if (
radius 10radius 10;
    }

    
_time32(&time);
    
_localtime32_s(&newtime, &time);
    
EE::Str t newtime.tm_hour ":";
    if (
newtime.tm_min 10) {
        
+= "0";
    }
    
+= newtime.tm_min;
    
timeText->set(t);

    
Vec2    worldMin pos radius,
                
worldMax pos radius;

    
Vec2    imageMin        Game::World.mini_map.worldToImage(worldMin),
                
imageMax        Game::World.mini_map.worldToImage(worldMax),
                
imageCenter Game::World.mini_map.worldToImage(pos            );

    
VecI2    imageMini        Floor(imageMin),
                
imageMaxi        Floor(imageMax);

    
Vec2    imageSize        rect.size() / (imageMax imageMin);

    
// iterate through all image maps to be displayed
    
for (Int y imageMini.y<= imageMaxi.yy++) {
        for (
Int x imageMini.x<= imageMaxi.xx++) {

            
// calculate screen position of the (x,y) image map
            
Vec2    imagePos rect.center() - imageCenter imageSize;
            
imagePos.+= imageSize.x;
            
imagePos.+= imageSize.y;

// draw image
            
Image &image Game::World.mini_map(VecI2(xy));
            if (
image.is()) {
