Reconcile actors. This is called after loading a level. It attempts to match each existing Viewport to an actor in the newly-loaded level. If no dec

Remember actors.

Change the actor's base.

Output a vector.

Split with plane. Meant to be numerically stable.

Select all adjacent polygons (only coplanars if Coplanars==1) and return number of polygons newly selected.

Transform this model by its coordinate system.

Unlock the viewport window. If Blit=1, blits the viewport's frame buffer.

FOutputDevice interface.

Mouse clicking.

Draw a circle.

Export this class property to an output device as a C++ header file.

Calculate the signed distance (in the direction of the normal) between a point and a plane.

Compare two points and see if they're the same, using a threshold. Returns 1=yes, 0=no. Uses fast distance approximation.

UTexture accessors.

Return this portal polygon, facing outward from leaf iLeaf.

WPropertiesBase interface.

Coordinate system inverse.

Determine if BlockingActor should block actors of the given class. This routine needs to be reflexive or else it will create funky results, i.e. A->Is

Lock the transaction tracking object.

Mirror a vector about a normal vector.

Create a new viewport.

Free a linear span buffer in temporary rendering pool memory. Works whether actually saved or not.

Release the object on behalf of an Ole client.

Sees if this palette is a duplicate of an existing palette. If it is, deletes this palette and returns the existing one. If not, returns this palette.

Reset the input system's state.

Return the FRotator corresponding to the direction that the vector is pointing in. Sets Yaw and Pitch to the proper numbers, and sets roll to zero be

Select none.

WTerminal interface.

Progress text.

Calculate the length of a string built from a font, starting at a specified position and counting up to the specified number of characters (-1 = infin

Serialize a string.

Try switching to a new rendering device.

Unlock transaction buffer.

Wrapped printf.

Convert a Bsp node to an EdPoly. Returns number of vertices in Bsp node (0 or 3-MAX_NODE_VERTICES).

Return a DirectDraw error message. Error messages commented out are DirectDraw II error messages.

moveToward() move Actor toward a point. Returns 1 if Actor reached point (Set Acceleration, let physics do actual move) */

An a new item */

Add an object to the root array. This prevents the object and all its descendents from being deleted during garbage collection.

See if a rectangle is visible. Returns 1 if all or partially visible, 0 if totally occluded. Status: Performance critical.

Perform axial movement and rotation.

Freeform movement and rotation.

UnrealScript keywords to highlight.

Close the base channel.

Delete all unreferenced objects.

State checking.

Grind this polygon through the span buffer and: - See if the poly is totally occluded - Build a new, temporary span buffer for raster and span clippin

Create a channel.

Build a master scene frame.

Just draw an actor, no span occlusion.

Serialize helper.
