2. Introduction We need to consider a couple of topics Console commands Command Line parameters Recording video Copyright © 2015 Curt Hill

3. Console Commands These are also known as exec commands These can also be started from within UnrealScript The console is a command line interface From there we may enter commands not necessarily having to do with game play Copyright © 2015 Curt Hill

4. Opening the Console The console may be opened or closed by the tilde (~) key This also shuts the console Game play is not suspended when in console –Should only be done when nothing else is going on Copyright © 2015 Curt Hill

5. Screen Shot Copyright © 2015 Curt Hill

6. Commands Commands may be categorized thus: –General –Statistics –Display –Rendering –Physics –Movie Capture –Others A reference is at: https://udn.epicgames.com/Three/ConsoleCommands.html Copyright © 2015 Curt Hill

7. General Quit or Exit –Ends the game Open –Starts a new level –Does not work in PIE –The level to start on may be specified on command line Copyright © 2015 Curt Hill

8. Statistics Stat fps –Shows the time elapsed and frames per second that it is rendering Stat game See next screen Copyright © 2015 Curt Hill

9. Game and FPS Copyright © 2015 Curt Hill

10. Others Mem –Will show memory allocation Viewmode – the same parameters as in editor –LightingOnly –DetailLighting –Wireframe Copyright © 2015 Curt Hill

11. Demos DEMOREC - Record a demo for later playback. DEMOSTOP - Stop demo playback\recording. DEMOPLAY - Play a previously recorded demo. Demos are stored in UDKGame\Demos –Only in the game not pie –Do no have the same view as play –Only playable in UDK Copyright © 2015 Curt Hill

12. Screen Shot SHOT – Takes a screenshot at the current screen resolution. Occurs immediately, so console version is sort of pointless Should use an exec command to do during game play Copyright © 2015 Curt Hill

13. Movie Capture Startmoviecapture Stopmoviecapture Captured movies end up in: …\UDKGame\MovieCaptures They are not really movies but.AVI files –There is no sound The bad news about.AVIs is there is no compression –10 seconds per gigabyte for full resolution Copyright © 2015 Curt Hill

14. Command Line There are several commands that you can enter via command line Recall that we set up the original icon with: udk.exe editor –log If the game is to be played with a specific level that should be the first parameter instead of the editor There are other parameters as well Copyright © 2015 Curt Hill

15. Where? In a Windows environment the command line occurs in several places: –In a DOS box –In a.BAT file –In the target item of the properties of a desktop icon –Menu properties Copyright © 2015 Curt Hill

16. Right Click Icon Properties Copyright © 2015 Curt Hill

17. The Program The first part of the command line is the executable: –UDK.EXE –The.exe is optional This is followed by a space and the world that you want to execute –This has a.UDK extension, which is optional Most command line parameters follow and are separated by blacks That is not the case for a few Copyright © 2015 Curt Hill

18. Specifics There are several parameters that must follow the level, separated by a question –Game=GameInfo class –Class=Pawn class Both of these prefixed by the directory of your mods These are attached to the.UDK file and separated by a ? UDK.exe demo2_c2.udk?game=CurtMod.CurtGameInfo?class= CurtMod.CurtPawn Copyright © 2015 Curt Hill

19. Command Line Parameters You may set the size of the window, that is its resolution with: –SetX=xxx –SetY=yyy Frames per second is: –FPS=xx –30 is needed for video Benchmark is needed to process each frame so no skips occur Copyright © 2015 Curt Hill

20. Making a Movie To do properly needs hardware capture or good software capture With just UDK and a movie maker a no-audio version can be made This requires several steps: –Record –Convert Copyright © 2015 Curt Hill

21. Record Start UDK with the following command line parameters: –Level resx resy benchmark fps –Such as: demo2_c2 resX=1024 resY=530 benchmark fps=30 Enter console –StartMovieCapture Do what is to be demonstrated Console –StopMovieCapture and Quit Copyright © 2015 Curt Hill

22. Convert Load up Pinnacle Studio Import the.AVI Clip off the beginning and ending console Create a file –Use the MPEG-1 encoding Copyright © 2015 Curt Hill
