Yes, cuts out around 80%. Yes, looks wrong, and yes is difficult to ignore. Was it always like that, or is it a recent change?m4r35n357 wrote:Is it just me, or does the laser cut out when the temperature bar is well short of maximum . . . ? OK I'm probably not really losing any firing time, but it does look a bit odd once you notice it, and difficult to ignore from then on.
The laser firing circuits cut-off shortly before the laser reaches meltdown temperature. This is why you don't see the bar reaching full length.
The problem is that when someone posts before you, the buttons that come up suggesting you review what you've written are not logical and do not come up with what you think they say - I too have lost posts this way. I cannot remember the wording and location, but the default activity is to cancel your own post.Micha wrote:Hmm, ninja'd. And where is my post?

Nothing in principle to stop the gauge indicating maximum at the cut-off point itself is there? Just seems like a waste of accuracy to me . . .You only need to fix stuff that is broken and this is not broken. When designing a laser there is always a small variation in specifications. To prevent the laser from burning completely you need a cut-off temperature were even bad maintained lasers stop when getting hot. Its for your own safety.m4r35n357 wrote:[Nice bit of handwavium
So is there something in the game core that makes this hard to fix?
Code: Select all
if (weapon_temp / PLAYER_MAX_WEAPON_TEMP >= 0.85)
{
[self playWeaponOverheated];
[UNIVERSE addMessage:DESC(@"weapon-overheat") forCount:3.0];
return NO;
}
Perhaps, just maybe, as an experiment, that 0.85 could be changed to 0.9 so it wasn't quite so obvious? And, you know, if lots of people report melting lasers, it could be changed back to 0.85 in the next build.Eric Walch wrote:I see no easy way to fix this without the risk of occasionally completely melting a laser.

For the military laser the heat-up per shot is 8. The highest heating up is the mining laser with 10 per shot. So when setting the cut-off at 85% the temperature can still raise to 94.999% after the shot. So the 15% safety margin is in fact only a 5% margin when anticipating on the shot that might follow.Micha wrote:It could be improved (pseudo-code-ish as I haven't had time to look at the code, but weapon_temp_per_shot must be retrievable from somewhere):
Having worked with lasers in the past I understand perfectly, I just think appealing to physics in Oolite is a bit like Godwin's law . . .Eric Walch wrote:I see no easy way to fix this without the risk of occasionally completely melting a laser.

The problem is that the weapon temperature can increase above 85% under normal operation because the check is for current temperature, not expected temperature after this shot. So if it was capped for display at 0.85, what would happen is that you would fire, the temperature would go red-full, and then it would stay there for a little while before starting to decrease again.m4r35n357 wrote:But I'll bite, I still think this is a display issue, the HUD could just display the 85% as 100%, ie. display_temp = weapon_temp / 0.85, no?
Just had it happen to me.Micha wrote:Hmm, ninja'd. And where is my post? This is the second time a post of mine has gone missing because others posted in the meantime.

Since the subject has been brought up, I'd like to remind you that I once posted about declaring equipment energy requirements on the Wiki, thinking it could be of use for some OXPs, etc..Eric Walch wrote:For the military laser the heat-up per shot is 8.
