#13731 new defect

TWINE: The movement of the meca penguin is different from dos version

Reported by: mgerhardy Owned by:
Priority: normal Component: Engine: TwinE
Version: Keywords: collision-detection
Cc: Game: Little Big Adventure


This issue was reported on the lba discord:

This is how it works in the original dos version and how it always worked. (screencast 192921)

This is what it does in the scummvm version (screencast 193231)

I am 100% sure it did not meander in lba1
That's the way I've been passing the Temple of BU puzzle since 94
Stand on the pressure plate, move a few steps back, release the penguin
and then go wait by the door

it does go straight, just in the wrong direction

there are different opinions about the issue - the meca penguin has random movement assigned - so it should meander

Still needs investigation.

99164665ba09fb09f6e855dbf1efb0faf33c250d fixed using the wrong penguin angle at spawn - but it still doesn't behave as shown in the video of the dosbox run.

TwinEEngine::processInventoryAction() case kiPenguin

after spawning the penguin is doing a rotation. that is unexpected.

comment:5 by mgerhardy, 13 months ago

actor->brickCausesDamage() returns true for the penguin. Looks like the issue might also be connected to the tank issue in

a hack is in place now - see

bIsFalling being 1 results in calls for doDir() which in turn rotates the penguin

comment:8 by mgerhardy, 5 months ago

the life script lINIT_PINGOUIN would have set that actor to dead - but unfortunately the collision detection was executed already for that actor and Animations::doAnim set the bIsFalling to true.
