Hi Sea Wolf,
That is strange, if it is the same power boat each time and there has been no change in the dynamics.
If the power boat has suffered any damage, its maximum speed will be reduced. I once had to deliberately produce damage via a trigger in a mission that raced a player PB against some AI PBs because the AI boats had a much lower max speed.
Another possible cause is a difference in FPS due, perhaps, to the addition of AI or Static ships to the mission. This could only change the indicated max speed if the boat was still accelerating at the end. This is because Mission Time passes more slowly at lower FPS, and it takes longer for a boat to reach maximum speed. However, the distance required should stay the same.
Without knowing the whole mission story, I guess that just setting the speed condition conservatively is the simplest solution.
If you want to post the mission.xml file, encapsulated in a compressed (.zip) folder, I’ll experiment to see if I can come up with an answer. I don’t need the .png file, but the .xml file will be corrupted if not protected in a .zip.
Regards,
Marty
