c# - Constraining X and Y Draggable Area -

-

i'm trying limit draggable area objects on screen , i'm getting few errors in code - trying keep simple now, reset the max x or y if object gets dragged beyond limits, i'm still not having success. use understanding how this.

    float maxdragx = 1000;     float maxdragy = 700;      vector3 mouseposition = new vector3(eventdata.position.x, eventdata.position.y, distance);      transform.position = mouseposition;                                 // set object coordinates mouse coordinates      if(transform.parent.gameobject == partspanel)     {         transform.setparent(draglayer.transform);                       // pop object draglayer move object out of partspanel     }      if(transform.parent.gameobject == buildboard)     {         // constrain drag boundaries of buildboard code         if(transform.position.x >= maxdragx)             transform.position.x = new vector3(maxdragx, mouseposition.y, distance);          if(transform.position.y >= maxdragy)             transform.position.y = new vector3(mouseposition.x, maxdragy, distance);     }

you cant set vector position.x or position.y float just. have change position completely

 float maxdragx = 1000;     float maxdragy = 700;      vector3 mouseposition = new vector3(eventdata.position.x, eventdata.position.y, distance);      transform.position = mouseposition;                                 // set object coordinates mouse coordinates      if(transform.parent.gameobject == partspanel)     {         transform.setparent(draglayer.transform);                       // pop object draglayer move object out of partspanel     }      if(transform.parent.gameobject == buildboard)     {         // constrain drag boundaries of buildboard code         if(transform.position.x >= maxdragx)             transform.position = new vector3(maxdragx, mouseposition.y, distance);          if(transform.position.y >= maxdragy)             transform.position = new vector3(mouseposition.x, maxdragy, distance);     }

i'm using unity3d networked multiplayer online game have large complex 3d terrain scene forest, trees, cliff, hills, mountains, bounders, etc. players can build structures sort of minecraft, , put them anywhere in scene, or move them around anytime. aside human controlled players, there automated ai players , objects animals roaming around scene following path. the problem how make these automated ai players , animals, able navigate around static , dynamic player created structures, because path follow can blocked player created structures, or other players , other ai objects, cliffs etc. have find away around them or on track if tumble down off high cliff example. so made navmesh , used navagents, takes care of static, non moving objects, how make ai players navigate around each other , dynamic structures created players can number in hundreds? i thought of adding navmeshobstacle everything, result in being attached hundreds of objects since user created structures b...
