Trees of Parts

Vessels in KSP are comprised of a number of parts, connected to one another in a tree structure. An example vessel is shown in Figure 1, and the corresponding tree of parts in Figure 2. The craft file for this example can also be downloaded here.

../../../_images/parts.png

Figure 1 – Example parts making up a vessel.

../../../_images/parts-tree.png

Figure 2 – Tree of parts for the vessel in Figure 1. Arrows point from the parent part to the child part.

Traversing the Tree

The tree of parts can be traversed using the attributes krpc_SpaceCenter_Parts_Root(), krpc_SpaceCenter_Part_Parent() and krpc_SpaceCenter_Part_Children().

The root of the tree is the same as the vessels root part (part number 1 in the example above) and can be obtained by calling krpc_SpaceCenter_Parts_Root(). A parts children can be obtained by calling krpc_SpaceCenter_Part_Children(). If the part does not have any children, krpc_SpaceCenter_Part_Children() returns an empty list. A parts parent can be obtained by calling krpc_SpaceCenter_Part_Parent(). If the part does not have a parent (as is the case for the root part), krpc_SpaceCenter_Part_Parent() returns nullptr.

The following Cnano example uses these attributes to perform a depth-first traversal over all of the parts in a vessel:

#include <krpc_cnano.h>
#include <krpc_cnano/services/space_center.h>

  krpc_SpaceCenter_Part_t root;
  krpc_SpaceCenter_Parts_Root(conn, &root, parts);

  typedef struct {
    krpc_SpaceCenter_Part_t part;
    int depth;

  stack[stackPtr].depth = 0;

  while (stackPtr >= 0) {

    int depth = stack[stackPtr].depth;
    stackPtr--;  // Pop the stack

    krpc_SpaceCenter_Part_Title(conn, &title, part);
    for (int i = 0; i < depth; i++)
      printf(" ");
    printf("%s\n", title);

    krpc_list_object_t children = KRPC_NULL_LIST;
    krpc_SpaceCenter_Part_Children(conn, &children, part);
    for (size_t i = 0; i < children.size; i++) {

Attachment Modes

Parts can be attached to other parts either radially (on the side of the parent part) or axially (on the end of the parent part, to form a stack).

For example, in the vessel pictured above, the parachute (part 2) is axially connected to its parent (the command pod – part 1), and the landing leg (part 5) is radially connected to its parent (the fuel tank – part 4).

The root part of a vessel (for example the command pod – part 1) does not have a parent part, so does not have an attachment mode. However, the part is consider to be axially attached to nothing.

The following Cnano example does a depth-first traversal as before, but also prints out the attachment mode used by the part:

#include <krpc_cnano.h>
#include <krpc_cnano/services/space_center.h>

int main() {
  krpc_connection_t conn;
  krpc_open(&conn, "COM0");
  krpc_connect(conn, "InfernalRobotics Example");

  krpc_SpaceCenter_Vessel_t vessel;
  krpc_SpaceCenter_ActiveVessel(conn, &vessel);

  krpc_SpaceCenter_Parts_t parts;
  krpc_SpaceCenter_Vessel_Parts(conn, &parts, vessel);
  krpc_SpaceCenter_Part_t root;
  krpc_SpaceCenter_Parts_Root(conn, &root, parts);

  typedef struct {
    krpc_SpaceCenter_Part_t part;
    int depth;
  } StackEntry;
  StackEntry stack[256];
  int stackPtr = 0;
  stack[stackPtr].part = root;
  stack[stackPtr].depth = 0;

  while (stackPtr >= 0) {
    krpc_SpaceCenter_Part_t part = stack[stackPtr].part;
    int depth = stack[stackPtr].depth;
    stackPtr--;  // Pop the stack
    bool axially_attached;
    krpc_SpaceCenter_Part_AxiallyAttached(conn, &axially_attached, part);
    const char * attach_mode = axially_attached ? "axial" : "radial";
    char * title = NULL;
    krpc_SpaceCenter_Part_Title(conn, &title, part);
    for (int i = 0; i < depth; i++)
      printf(" ");
    printf("%s - %s\n", title, attach_mode);

    krpc_list_object_t children = KRPC_NULL_LIST;
    krpc_SpaceCenter_Part_Children(conn, &children, part);
    for (size_t i = 0; i < children.size; i++) {
      // Push onto the stack
      stackPtr++;
      stack[stackPtr].part = children.items[i];
      stack[stackPtr].depth = depth+1;
    }
  }
}

Fuel Lines

Figure 5 – Fuel lines from the example in Figure 1. Fuel flows from the parts highlighted in green, into the part highlighted in blue.

../../../_images/parts-fuel-lines-tree.png

Figure 4 – A subset of the parts tree from Figure 2 above.

Fuel lines are considered parts, and are included in the parts tree (for example, as pictured in Figure 4). However, the parts tree does not contain information about which parts fuel lines connect to. The parent part of a fuel line is the part from which it will take fuel (as shown in Figure 4) however the part that it will send fuel to is not represented in the parts tree.

Figure 5 shows the fuel lines from the example vessel pictured earlier. Fuel line part 15 (in red) takes fuel from a fuel tank (part 11 – in green) and feeds it into another fuel tank (part 9 – in blue). The fuel line is therefore a child of part 11, but its connection to part 9 is not represented in the tree.

The attributes krpc_SpaceCenter_Part_FuelLinesFrom() and krpc_SpaceCenter_Part_FuelLinesTo() can be used to discover these connections. In the example in Figure 5, when krpc_SpaceCenter_Part_FuelLinesTo() is called on fuel tank part 11, it will return a list of parts containing just fuel tank part 9 (the blue part). When krpc_SpaceCenter_Part_FuelLinesFrom() is called on fuel tank part 9, it will return a list containing fuel tank parts 11 and 17 (the parts colored green).

Staging

../../../_images/parts-staging.png

Figure 6 – Example vessel from Figure 1 with a staging sequence.

Each part has two staging numbers associated with it: the stage in which the part is activated and the stage in which the part is decoupled. These values can be obtained using krpc_SpaceCenter_Part_Stage() and krpc_SpaceCenter_Part_DecoupleStage() respectively. For parts that are not activated by staging, krpc_SpaceCenter_Part_Stage() returns -1. For parts that are never decoupled, krpc_SpaceCenter_Part_DecoupleStage() returns a value of -1.

Figure 6 shows an example staging sequence for a vessel. Figure 7 shows the stages in which each part of the vessel will be activated. Figure 8 shows the stages in which each part of the vessel will be decoupled.
