I think you are meaning to say f24_swa instead of f49_swa. f24_swa is the one with 7 input arguments, six floats and one integer (index). Index of what by the way? Also, have you considered those six floats instead of two points could be a ray and a plane?


Anyway, f49_swa has constant input:
50 50 248 -248 192 -192
50 50 20 -20 20 -20

...until it changes to:
50 50 248 -248 192 -192
50 50 80 -80 80 -80

The change occurs and lasts eleven frames when a new torpedo target is acquired (yellow bracket), and then it goes back to usual. Speaking of which, there is a bug with this targeting system and also spawning/moving of Tie fighters. Target acquisition system should release a target at some point when outside of field of view, but it doesn't always. And then to make it worse these locked-on Tie fighters either move or re-spawn at very far distance away. So first you can't use torpedoes on nearby targets when all three target locks are taken, and second you can't approach these far away Tie's to take them down and complete a level.
