Scripting an MMO map

[ItHadToComeToThis]

Okay my fine scripters. I have given it a go and i have come to a standstill on the next part. So far, this is working but only works on a square face. What i want to do is have it working on a round face. I know i will have to extend the map edges in some way and modify my calculations but i am a tad stumped on how to go about it.

If you put this on a circular face as it is the marker goes off the circle and assumes its still a square. If anyone can help me figure the next part out i will be eternally grateful.

Note : If you want to use what i have done so far and adapt it to your needs i really do not mind, go ahead.

You need a square prim on your HUD with a smaller square/cylinder in front of it.

string makeURL(string region){
    return "http://api.gridsurvey.com/simquery.php?region="+llEscapeURL(region);
}
string regionTexture;

    }

        integer find=llListFindList(llList2ListStrided(parse,0,-1,2),["terrain_uuid"]);
        if(-1!=find){
            regionTexture=llList2String(parse,(find*2)+1);
            llSetLinkTexture(4,regionTexture,-1);

what are the initial /relatives sizes of the 2 prims ?  what are their start positions ? and orientations ?

as wrote the linked prim barely moves, so is bit difficult to see what it is supposed to do

 

edit add

normally tho, with a point within a circle then we would check that the 'final' distance from the centre of the root prim is within the radius of the circle

Urghh I put the wrong script in. I was at work and at the end of my shift and sorting stuff out. Posted in the hopes of some discussion by the time I got home. The one I posted was a much earlier version. The one listed now should display the sim map, zoomed in. The object should stay in the centre of the hud and move the texture instead

ok i have a play with it and see what I can do

[Mollymews]

i had a quick play. Is not simple

when the marker is on the circumference, the marker should not move. And the texture map has to move in the opposite direction on the relative X or Y axis,  from the direction it moves when the marker is inside the circle

i will have to think about how to code that

edit add:

i played with it a bit more and the biggest (aesthetic) issue with a circle is that when the marker cannot move outside of the circle (into the corners of the region/arena), and the map texture is moved to the true postion then another texture representing the region boundary (and next region over) needs to be displayed also within the circle for it to look good

for a MMO I would go with the square map, as most players are already used to arena maps being square

also I would not use a timer for this. I would llTakeControls and update the map on keydown

relative X or Y axis

i just stick a simple diagram here to show what has to happen with a square arena and a circular viewpoint

 

green is the arena. Red is the arena border.  Black is the edge of our viewport.  Blue/white is the player marker

 

to do what we want then we create our own texture map of our arena, which is 2 times the size of the arena. Where the green (arena) is centered on the texture with a border (red). Then we can scale/scroll the arena texture. Preventing the marker from moving beyond the circumference of the viewport

Aha so its double the size. That was one of the issues I was facing. I wasn't sure how much bigger to make it. I have further plans for it once this is figured out fully. Rotating as you turn, markers that appear on map the closer you get and "highlight" around the edge when further away. But first...this issue. Should be simple enough thinking about it if its only double the size. I just have to do the same thing but contained in a smaller square as opposed to the whole texture. Thank you btw much appreciated :)

double the size

another diagram about the size to confirm double

when the player marker is on the boundary, say at the top of the map on the center line then the marker can't move left or right, so the map scrolls. Same with the other X Y center lines.  And the map looks like this
