MOHAWK: Riven: Screen doesn't fade to black when capturing Gehn.

[macca8]

This report refers to the second meeting with Gehn (having previously met before the trapbook was recovered), where the player returns to his office and gives him the trapbook.

If the player chooses to enter the trapbook when prompted, instead of the screen fading to black, it freezes with the image of Gehn holding the book. The movie plays as expected, but the image remains in the background (see attached screenshots) until the sequence completes.

To reproduce, using the attached saved game, enter the trapbook when prompted by Gehn.

What happens next is inconsistent.

Sometimes the game continues as normal, but I'm concerned that other times it will simply crash (bus error).
If it's going to crash, it's generally when the cursor reappears (either after Gehn's capture is complete or, if the trapbook is ignored, when he leaves the office).

Player is inside book.

[macca8]

Gehn considers his decision.

[macca8]

Gehn captured!

[macca8]

Link to office, enter trapbook when prompted.

Sorry, forgot to mention. The trapbook performs correctly at all other meetings. The crash is unique to this meeting.

I originally played through this part recently on the DVD version on commit:
0e2d14ac415faeec25226cef64b3443b0905eff9 (August 8). I only went through that part once, but I do recall there being a long delay after entering the book and the movie for gehn entering the book starting (it showed a black screen for a lot longer than usual).

So I did encounter something, but since I only played through once I will test this part more thoroughly to see what exactly the dvd version does, later today.

This is a script bug specific to the CD version of the game. The script tries to change card during a screen update and while still loading the previous card ...

CD version script:

== Script 1 ==
type: CardUpdate
switch (agehn) {
	case 1:
		switch (atrapbook) {
			case 1:
				obutton = 1;
				transition(16);
				switchCard(2);
				break;
		}
		break;
	case 2:
		activatePLST(5);
		break;
	case 3:
		activatePLST(5);
		break;
}

DVD version script:

== Script 1 ==
type: CardUpdate
switch (agehn) {
	case 1:
		switch (atrapbook) {
			case 1:
				obutton = 1;
				activatePLST(6);
				break;
		}
		break;
	case 2:
		activatePLST(5);
		break;
	case 3:
		activatePLST(5);
		break;
}

== Script 2 ==
type: CardEnter
switch (agehn) {
	case 1:
		switch (atrapbook) {
			case 1:
				obutton = 1;
				transition(16);
				switchCard(2);
				break;
		}
		break;
}

I'll patch the script to match the DVD version.

I've added the script patch in commit ee588a8. Should work fine now. Thanks for your report.
