HasRequirements

Reads requirements from the given CBitStream into variables you provide.

This is primarily for use in conjunction with other requirement-handling methods.

The requirements parameter is the CBitStream you're reading the requirements from. The missing parameter is a CBitStream that any missing requirements will be read into.

bool hasRequirements( CInventory@ inventory1, CInventory@ inventory2, CBitStream@ requirements, CBitStream@ missing )

Example from Entities/Workshops/Scripts/WorkshopTasks.as:

void AddWorkshopTasksButtons( CBlob@ this, CBlob@ caller, CGridMenu@ menu )
{
  int tasksCount = this.getProperties().getScriptObjectGroupSize( "tasks" );
  if (menu !is null)
  {
    for (int i = 0; i < tasksCount; i++)
    {
      WorkshopTask @wt = cast<WorkshopTask@>(this.getProperties().getScriptObject( "tasks", i));
 
      CBitStream bsMissing;
      CBitStream combinedReqs;
      if (hasRequirements( this.getInventory(), caller.getInventory(), wt.requirements, bsMissing ))      {
        CBitStream params;
        params.write_u16(caller.getNetworkID());
        CGridButton@ button = menu.AddButton( wt.iconName, wt.name, WshpTasks::make_task + i, params );						
        SetButtonRequirementsText( button, wt.requirements, false );	
      }		
      else
      {
        CGridButton@ button = menu.AddButton( "$NONE$", wt.name, WshpTasks::nil );
        SetButtonRequirementsText( button, bsMissing, true );	
      }
    }
  }
