SQ2: Walk glitch

Reported by: eriktorbjorn Owned by: eriktorbjorn
Priority: normal Component: Engine: AGI

Cc: Game: Space Quest 2


English DOS version Latest SVN snapshot

After you have crash landed on the planet, if you walk towards the wreckage from behind, Roger doesn't stop until he's visible through the wreckage. This glitch does not happen with DOSbox or NAGI.

It could be a problem with checkPriority(). If I change that to always return 1, I can walk right through the wreckage. The corresponding function in NAGI appears to be obj_chk_control().

NAGI's objs_step_update() triggers when Y reaches 144 to move you back to 143. Our updatePosition() triggers when Y reaches 145 and moves you back to 144. Assuming they handle coordinates the same way, something's different.

(This was tested with a rather old version of NAGI. I haven't checked if there's a newer one.)

Sev, we have tons of AGI reports by now, but do we have anybody who is interested in looking at them? Looking at AUTHORS, I see aquadran, darkfiber, dsx and you listed. As it is, there seems to be zero activity (this is not meant as critcism, just an observation). So, maybe we should either try to contact all of the above and ask them whether they are interested in looking at some of the reports; or we could try to find other interested people. (and maybe if I am really bored, I'll have a look at some of these issues myself, but I have no experience so far with AGI).
