Quest Idea - Compass , Warm Cold Directions, Find Location

[Muratus del Mur]

This is not sample code, it is just a note on a possible quest concept i was thinking.

by using uv(location) on an item, to determine someones current location, you could create a list of locations and based on that you could return a message like "you are getting close" or a direction indication like "go left until you find a tree". In this way you could create items like a compass that will point you to a predefined location the editor picks, or quests like treasure hunting.

If you combine this with the storage and the date functions you could for example ask someone to find the propper place for some seeds to grow, considering soil, light or anything else you want. The quester will have to wait one day in a place to see if the seeds start to grow or not, then try an other one. The one that manages to get them grow first wins.

Other things like a dynamic map direction items are possible in the same way, all you need to do is to use the location of the current player and prepare a list of responses based on that location.

Maybe someone can point out why this might not work, or provide a sample code for it.

Mur, you are giving it away.

i was discussing a topic about a possible compass in md, when i realised how many things could be done with the location spell combined with inventory items. I didn't saw anyone using it so i thought to place it on forum. Sorry if i spoiled any of your ongoing quests.

My attempt at creating a compass is up now [url="http://magicduel.invisionzone.com/topic/8032-missing-cards/"]here[/url]. Once it has run, I will post some of the code here. Any comments or questions are welcome.

Create an array of locations. This was originally two functions that were used at different points in the quest but I realized that I could combine them. This is the result.
[code]function create_locations(@vm=array('all')){
//allowed values: nomansland, marindbell, mda, labyrinth, tribunal, loreroot, golemus, necro
@vl=array();
if(in_array('nomansland', @vm) OR in_array('all', @vm)){

}

Distance and direction
[code]//@vf - user's location
//@vg - location of target item (card)
//@vw - array of locations
function find_degree(@vf, @vg, @vw){
if(@vf != @vg){
foreach(@vw as @vu){
if(@vu[0] == @vf || @vu[0] == @vg){
if(@vu[0] == @vf){
// u ser location found in array
@vh['me']['x'] = @vu[2];
@vh['me']['y'] = @vu[3];
} else {
//ne xt card location found in array
@vh['card']['x'] = @vu[2];
@vh['card']['y'] = @vu[3];
}
}
}
} else {
foreach(@vw as @vu){
if(@vu[0] == @vf || @vu[0] == @vg){
if(@vu[0] == @vf){
@vh['me']['x'] = @vu[2];
@vh['me']['y'] = @vu[3];
@vh['card']['x'] = @vu[2];
@vh['card']['y'] = @vu[3];
}
}
}
}
if(@vh['me']['x']-@vh['card']['x'] AND @vh['me']['y']-@vh['card']['y']){
@vh['distance'] = sqrt(pow(@vh['me']['x']-@vh['card']['x'],2)+pow(@vh['me']['y']-@vh['card']['y'],2));
@vh['deg'] = compas(@vh['me']['x']-@vh['card']['x'], @vh['me']['y']-@vh['card']['y']);
} else{
@vh['distance'] = max(@vh['me']['x']-@vh['card']['x'], @vh['me']['y']-@vh['card']['y']);
@vh['deg'] = compas(@vh['me']['x']-@vh['card']['x'], @vh['me']['y']-@vh['card']['y']);
}
return @vh;
}

//compass function was copied directly from php.net documentation
function compas(@vx, @vy){
if(@vx==0 AND @vy==0){ return 0; }
return (@vx < 0)
? rad2deg(atan2(@vx,@vy))+360
: rad2deg(atan2(@vx,@vy));
}[/code]

find_degree was never optimized but it worked. For some reason 0 degrees came out as due south when I was expecting it to be east but that was an easy fix.

Of course if you were using this in an item with a locate spell you would have to increase the locations array to cover all map locations.
