unity3d - Using C# IComparer in Unity game engine -



unity3d - Using C# IComparer in Unity game engine -

i writing border class graph a* implementation. want later create list of edges , sort them based on border weights using icomparer interface.

below implementation of border class within unity 4.5f

using unityengine; using system.collections; public class border : icomparer { node destination; int weight; public edge(node destinationnode, int cost) { destination = destinationnode; weight = cost; } public node getdestination() { homecoming destination; } public int getcost() { homecoming weight; } int icomparer.compare(system.object a, system.object b) { if (((edge)a).getcost() == ((edge)b).getcost()) homecoming 0; else if (((edge)a).getcost() > ((edge)b).getcost()) homecoming 1; else homecoming -1; } }

but unity throws below error

argumentexception: not implement right interface system.collections.generic.comparer`1+defaultcomparer[edge].compare (.edge x, .edge y) (at /users/builduser/buildslave/mono-runtime-and-classlibs/build/mcs/class/corlib/system.collections.generic/comparer.cs:86)

i tried using icomparer<edge> throws error

the non generic type 'system.collections.icomparer' cannot used type arguments

unity not allow me utilize icomparable not understand when seek utilize :( throws

" type or namespace not found "

i don't know whats wrong. please help me out?

i think unity expects implement icomparable<edge> (generic version of icomparable, please see http://msdn.microsoft.com/fr-fr/library/4d7sx9hd%28v=vs.110%29.aspx )

this implementation close yours, except doesn't need casts (since input types edge)

c# unity3d
