I trying to complete a RPG game for a project, but have no idea on how to make the game map. It doesn't need to be graphical, but the code for the whole map and each tile must be correct. So far, I thought about making a non-matricial map (as request by the professor) by using an ArrayList which contain all the linked tiles. public abs...
A Java API returns a java.util.Map<java.lang.String,java.lang.Boolean>;. I would like to put that into a Map[String,Boolean] So imagine we have: var scalaMap : Map[String,Boolean] = Map.empty val javaMap = new JavaClass().map() // Returns java.util.Map<java.lang.String,java.lang.Boolean> You can't do Map.empty ++ javaMap, because t...
I need to store key/value info in some type of collection. In C#, I'd define a dictionary like this: var entries = new Dictionary<string, int>(); entries.Add("Stop me", 11); entries.Add("Feed me", 12); entries.Add("Walk me", 13); Then I would access the values so: int value = entries["Stop me"]; How do I do this in Java? I've see...
The following code does not want to compile. See the included error message. Code: #include <map> #include <vector> #include <iostream> class MapHolder { public: std::map<std::vector<std::string>,MapHolder> m_map; void walk_through_map() { std::map<std::vector<std::string>,MapHolder>::iterator it; for(it = m_map.beg...
I'm working on an application in Flex will utilize mapping features. I have experience with the Google Maps API in Flex, but it seems sort of limited to me (as compared to other APIs and the Javascript API). In particular, I'm interested in developing some clustering (grouping places together to prevent too many points from being on the ...
I have a list of tuples: X = [{"alpha","beta"},{"gamma","theta"}]. I want to print X as a flat string using, io_lib:format("~s", [X]) in the following format: [{"x":"alpha", "y":"beta"}, {"x":"gamma", "y":"theta"}] How do I achieve this? I started using Map to do transform the list. But I was not able to print it as a string...(ga...

I'm intersecting some sets of numbers, and doing this by storing a count of each time I see a number in a map. I'm finding the performance be very slow. Details: - One of the sets has 150,000 numbers in it - The intersection of that set and another set takes about 300ms the first time, and about 5000ms the second time - I haven't don...
Hi, I'm facing a problem that seems to have no straighforward solution. I'm using java.util.Map, and I want to update the value in a Key-Value pair. Right now, I'm doing it lik this: private Map<String,int> table = new HashMap<String,int>(); public void update(String key, int val) { if( !table.containsKey(key) ) return; Entry...

I am considering a factory function to create different classes in the same hierarchy. I understand that normally a factory is normally implemented as follows: Person* Person::Create(string type, ...) { // Student, Secretary and Professor are all derived classes of Person if ( type == "student" ) return new Student(...); if ...
I am getting this error when the map loads. The error is in the original, unmodified OpenLayers.js file on this line: return!!(document.namespaces); I have tried rewriting it to: return (typeof(document.namespaces) != 'undefined'); and it worked but then I get same "unspecified" errors on further referrals to document.namespaces: ...
In the code below, why it is that when I take the address of a map index (which contains a list) and I take the address of the list itself, they both have different values. See the code below for clarification. #include <iostream> #include <list> #include <map> using namespace std; int main() { list<char> listA; //list of chars...

I have attached a mapview to my layout and have a it showing a compass and my current location, the problem I have is that there is no street map shown in the view, so basically I just see the compass and my current location over a blank grid. ...
I currently have a std::map<std::string,int> that stores an integer value to an unique string identifier, and I do look up with the string. It does mostly what I want, except for that it does not keep track of the insertion order. So when I iterate the the map to print out the values, they are sorted according to the string; but I want ...
SO, I am getting down to the wire on a deadline for an HTML/Flash hybrid interactive map, and it is not anywhere near finished. I keep getting close to solving each problem, only to discover more bugs. Most of them are quite obvious when you look at the work. I would like to at least squash the big bugs, so I am VERY appreciative of any ...
