Patch:Oracle Council Message

From KeenWiki
Jump to: navigation, search

Council Members are red robed figures Keen must rescue in Keen 4 to win the game. Eight must be found and touched, whereupon a text window will appear and the level will be exited.

This page deals with the text boxes and what happens. (Music changes, a member is rescued, level ends...) For what the member sprites do and how they behave, see Patch:Council Member.


Disable

These patches disable various aspects of the council messages


Completely disable message

This patch completely disables the member message, touching the member (Or any sprite with sprite type 6.) will have no effect... unless Keen is in the Oracle Janitor level, since the Oracle janitor is not affected. Notice however that the message activation code that this skip (See section below) also checks if the game is won, so using just this patch will cause the game to be incompleteable.

Patch: Keen 4
#Completely disable Council Member messages
%patch $CD93 $13


Disable both message windows

This patch disables the message windows and saving the council member. Touching a member plays a sound then wins the level.

Disable Elder's window

This patch removes the Elder's window so only Keen's reply appears.

Disable Keen's reply, save elder

This patch removes Keen's reply textbox entirely, that is, all that will appear is the Elder's window. (Which can have only one of two different messages, normal or underwater.) The level will then be exited. The council member is however, saved.

Notice this affects the patch relating to what gets saved; the brown value is what is increased by 1 every time an elder is saved, if using this patch changes must be made there instead of using the patch that appears elsewhere on this page.

Patch: Keen 4
#Don't display Keen's reply boxes to the Gnostice Ancients

Keen doesn't exit level after meeting a Member

This patch allows Keen to continue playing the level after meeting the Member. This is done by first changing the Member's type so it doesn't trigger the exit level sequence. The collision causes the Member to transform into a raindrop splash when Keen hits it (This can be changed.) so that Keen is not stuck in an infinite loop of messages. This patch uses the EGAGRAPH skip so is incompatible with other patches that use it. It also removes the only way to win the game by default, so some other way to win must be used.

Text Windows

These are the text windows that appear when Keen rescues a Council Member. There are two of them each time, the Member's, which is always the same (Except for one special level under water.) and Keen's, which become increasingly disrespectful each time. When the window appears the music changes, and when the conversation is over the level is exited and completed.


Images

The windows must cache the graphics they are using before they appear. In this case three sets of images are saved; Keen's head, the member's head and Keen giving a thumbs up. Notice that bitmaps are referred to by their 'chunk number', that is, what graphic chunk they are in EGAGRAPH.CK4; this is the bitmap number (When exported via ModKeen, Keengraph numbers the bitmaps 'correctly') plus six.

Patch: Keen 4
#Bitmap cache (3 bitmaps, 104-6)
%patch $F4AE $006EW
#Cache Council Member graphic
%patch $F4B5 $006FW
#Cache Talking Keen head
%patch $F4BC $0070W
#Cache Keen's thumbs up

Window Setup

Both of the windows displayed must be set up. There are five variables to consider; the size of the window in 8x8 tiles, the image shown in the window, how long the window is displayed (After the player presses a key.) and where the window's text is read from. (See Patch:Text patches).

Keen has several replies, a new one for each member saved. The window references a list of pointers to the various replies. (This will usually not need to be altered.) The reply used depends on how many members have already been rescued. (Starting with 0) It is possible to change this.

The location of the bitmap can also be changed; it is offset somewhat from he right of the window (It is centered vertically.) This is useful if the bitmap's size is changed. (Text cannot be drawn over the bitmap.)

Don't wait for the player to press a key

These patches remove the 'wait for key' code; that is, the window will automatically move on to the next window without the player pressing anything. This means the player must read the window within a certain period of time, and makes the conversation seem far more urgent.


Saving Council Members

The 'disable' patches in the first section of this page affect the saving of council members. These patches do so also, in a more direct way. Each window is separate, so either of both patches can be used.

Patch: Keen 4
#Remove Council Member wait-for-key
%patch $F52E $90 $90 $90 $90 $90
#Remove Keen's reply wait-for-key
%patch $F5A6 $90 $90 $90 $90 $90


How many must be saved

This check is run every time a level is exited. Keen will win the game by default if he has rescued eight council members. It is possible to change what is looked for, how many are required and the jump conditions.

The first value is what is looked for, the second how many and the third the jump condition.

Patch: Keen 4
#What wins game (Default 8 members)
%patch $6AE4 $7A5EW $08 $74


Check for underwater elder

By default the game displays the 'underwater elder' message when Keen is in level 15 ($11). It is possible to change what is checked for and what value it must have. (The default checks if current level = 15) It is possible to have the underwater message on several levels, or when Keen has a certain object.

Patch: Keen 4
#Check for underwater elder
%patch $F50F $A7EDW $11 $75


Different reply for each level

By default Keen's replies depend on how many members he has rescued already. This patch makes his reply dependent on what level he is in, much like how the Yorp messages work.

This patch creates a new list in a new location with space for 20 or more levels. In this case two sets of each reply are used, so level 1 and level 9 have the same reply. (The map level, level 0 has its own reply, identical to level 8's.) The replies used are in the same place as the standard replies.

If Keen is in a level with no pointer, odd stuff will occur.

Save Member sounds

There re two sounds played when the member is saved. The first is the same sound played as when Keen exits the level. It is not heard however because it is immediately 'overwritten' by the second sound. The second is specific to the council members.

Patch: Keen 4
#Sounds played when member saved
%patch $6AC0 $000DW
#Unheard 'exit' sound
%patch $CDAC $001FW
#Oracle sound


Don't play sound

This stops the sounds being played. Each patch is independent and either or both can be used. Note that if the second sound is blocked the first will be heard and if both are blocked it is possible that it may affect things like the Wetsuit or Princess Lindsey since the first sound may also play (But not be heard) when they are found.

Patch: Keen 4
#Block sounds played when member saved
%patch $6ABF $EB $0A
#First, unheard, sound
%patch $CDAB $EB $0A
#Second


Music

By default new music plays when the Oracle is being spoken to, and it is stopped afterwards. The song used is a unique one not used for other levels. See also Patch:Music.

Note that while the new music code is part of the Member window code, the 'stop old music' code is not. This may be important when the window code is called in an odd way. (Such as when a sprite dies.)


Music played

By default the song played is -1, a unique song. It can however be turned into positive values for other songs. In that case the value is not the song number, but rather the level number of what music is desired. (So a value of +1 will play the same music as plays in level 1.)

Patch: Keen 4
#Music played when Member is rescued
%patch $F4CA $FFFFW


Don't play any music (Silence)

This patch stops the music changing when Keen is talking to the Member. Instead there is silence. If this is combined with the following patch then the music will not change at all when the Member is rescued. (See below.)

Patch: Keen 4
#Silence while talking to Member
%patch $F4CD $90 $90 $90 $90 $90

Same music plays after Member rescued

If this patch is used the music remains the same. This is no consequence by default as the level then exits and the music stops anyway, but if other patches are used that allow Keen to keep playing the level then this will permanently change the level's music after the member has been rescued.

Note that the normal music will play if the game is saved then loaded.

Patch: Keen 4
#Same music plays after Member rescued
%patch $F5E7 $90 $90 $90 $90 $90


Message code

There are three sets of code run when a council member is saved. The first is a simple change of the 'level state' to 3 which then triggers the second set of code in the level loop. This in turn runs either the 'win game' or third set of code, which contains the actual message windows.


Change level state

This short patch is what changes the 'level state' to 3; checking out the linked page will show what happens if it is set to any other value. Note that changing this value will remove the only default way the game can be won.

This can be used anywhere in-game; in a sprite's behavior or collision of when Keen touches a tile. If it is replaced with a string of $90 then the message will be disabled. (This will also disable the 'win game' code.)

Replacing this string with $90s will stop the level state being changed at all, rendering the council member completely ineffective.

Patch: Keen 4
#Member message activation code
%patch $CDB7 $C7 $06 $7A70W $0003W


Level loop code

This code is run whenever the Council Member is saved. The first thing that happens is sound 13 is played. (Replacing the $9A $187409F1RL with $90 $90 $90 $90 $90 will stop the sound being played.

After this the current level is marked as done and the Council Member message windows appear. (This can be prevented by replacing the $$9A $0E8F0BA5RL with $90 $90 $90 $90 $90, we can also stop the level being marked as done by changing the $0001W to $0000W.)

The game then checks if exactly 8 members have been saved. If they haven't then sets the level to 0 (Map) and Keen goes there. Otherwise the 'win game' code is run. Notice this includes increasing Keen's score and the number of members saved.

Replacing the bytes $A1 $EDwith $EB $25 on the second line will make the game go directly to 'win game' when the member is contacted.

Level Keen goes to when saving a member

This is the level that Keen goes to when he saves a member. By default it is level 0, the map. But the Member can take him to any other level, even ones not reachable from the map. it is also possible to change the game stat changed so Keen restarts the level, but is given something else.

This patch is part of the above patch and thus incompatible with it.

%patch $6AEB $7A68W $0000W

Message window code call

This short patch is the 'activation code' for the council member windows; calling it will display the member windows and Keen's replies and will also save a council member. (The windows however are not cleared from the screen afterwards.) It can be used anywhere in the game. Notice that it will not run the win-game check and that it is part of the code in the above section.

Patch: Keen 4
#Message window activation code
%patch $6ADD $9A $0E8F0BA5RL


Misc

These are patches that do not fit into any section above.


Restart level when contacting Member

This patch causes the level to restart when a Member is contacted. The level is not completed, nor is the message displayed.

Patch: Keen 4
#Getting member restarts the level
%patch $6AB8 $E9 $00E1W


Exit but don't complete level when contacting Member

This patch causes the level to end but not be won when a Member is contacted. The level is not completed, nor is the message displayed.

Patch: Keen 4
#Exit but don't complete level when contacting Member
%patch $6AD7 $EB $09


Don't complete level when Member rescued

This patch stops the level being completed when a Member is rescued. The message appears, a Member is added to the 'rescued' counter, Keen returns to the map but the level itself is not completed and can be reentered.

Patch: Keen 4
#Mark a level as done when rescuing a member
