Topic on Talk:Tom Clancy's Splinter Cell

I did a bit of thinking, what if the AI's path finding is effected by the frame rate and how would that look different. And how do we know which frame rate results in the correct path finding.


My mind jumps straight to real time cutscenes, which Splinter Cell has only a few. The best is at the start of the Training level, where we can observe Lambert throughout the scene. And luckily differences are easy to spot, while Lambert walks down the corridor and during his final movement in the conference room(he walks from the side of the table to the end). each of the following were tested 10x

@ 30fps, 60fps: middle of corridor; stays close to the table and finds his mark.

@ 120fps, 144fps: diagonally(left to right) in corridor; takes a wide curve but finds the mark.

@ 147fps: diagonally(left to right) in corridor; 20% chance that he will have to backtrack.

@ 150fps: diagonally(left to right) in corridor; 70% chance that he will have to backtrack.

@ 200fps: diagonally(left to right) in corridor; 100% chance that he will have to backtrack.


When Lambert has to backtrack the cutscene looks terrible, like nobody cared about how it looked. I believe most will agree that 30fps and 60fps look to be the most natural looking path for Lambert to take. While at 120fps and 144fps the scene looks fine, it's only when comparing differences that they may look a little odd. So with this in mind I took a look at one other location in the game, the start of the Abattoir level. When Badri finishes his dialog and walks to the office. each of the following were tested 3x

@ 60fps: his movement is direct, to the point.
@ 120, 144fps: he takes a wider path and bumps into a concrete block.
@ 180fps: ??% chance his wide path means that he will trigger a mine, thus killing himself.
@ 200fps: his wide path means that he will trigger a mine, thus killing himself.


So with those to observations in mind, what's happening in the Vselka Infiltration level. I think we can assume that 1 or 2 of the AI are missing there mark(waypoint) and need to backtrack. While the last is still trying to move forward, thus creating a jam in the confined space.


I had planned to post a video to go with this, to help show what I'm trying to say, but my video editing skills are not that great.
