Correct me if I'm wrong here but, as far as I know small and small pulse lasers should have no ghost heat, right? Also mediums have ghost heat after 6 but, aren't linked with anything else?

Here is my issue:
Right now my mech has 2xML and 7xSL. In the testing ground when I fire the 2xML I get a spike up to 5%. Now, when I fire my 7xSL I get spike up to 15% some times 16%. If I fire the 2xML and wait .5 to fire the 7xSL I get around 20%, which would make sense. This is where I'm confused. When I alpha it spikes all the way up to 26% heat. Even if I don't alpha but, fire within the .5 seconds I spike up to 26%

What I would like to know is where does this extra 6% heat come from? They claim smalls have no ghost heat at all and mediums are not linked. Clearly something funky is going on here or I just don't understand how the ghost heat works at all. 6% heat from out of thin air is life or death in game, especially for energy based mechs.


Any clarification would be great, if this is a bug please address it.

How many HS do you have, and are they SHS or DHS?

I have 20 double's, incuding the engine.

are you moving when you fire at the sometimes, since moving also creates heat, and as Lynx has mention how many Heatsinks and type are you using ?, Also what map are you testing on since remember different map have different heat levels e.g. most mechs are at 7% heat at idle on terra terma

Nope, I'm not moving. All testing was done static. The reason I even tested this to begin with was because I had a few games that I felt I was getting weird heatspikes since I normally know what percent each weapon group will cause. I even had someone ask me on a hot map if I was using single heatsinks lol.

So just randomly working through the maths.

2 Med Lasers, each puts out 4 heat, total 8 heat.
7 Small Lasers, each puts out 2 heat, total 14 heat.

20 DHS, which grants .14 heat dissipate per second each so a total of 2.8 heat dissipation per second. If you fire 2 Med Lasers, wait 0.5s then fire 7 Sml Lasers, you will also have dissipation during the 0.5s, so effectively it's 8 heat -1.4 heat + 14 heat, which is 20.6 heat. If you alpha, there is no time for dissipation, then the total will be 22 heat.

So there is a difference of 1.4 heat between the two firing modes. What I don't get is how 1.4 heat = 6%. That simply doesn't match up well to anything.

This sounded weird and unlikely, so I loaded up my 4P with the same setup, and am actually getting the same issue. Stationary, with 7slas on one group, 2mlas on the other, I get 15% heat from slas, 5% from mlas, and 26% when fired as a single group.

It's possible it could be ghost heat, but another thing did occur to me- lasers generate heat continuously while they're burning. Given that the slas has a shorter burn time than the mlas, the heat buildup should be rapid for the duration of the slas and then slow down when just the mlas are burning at the end; but it looked like a steady, linear heat build. Might be an issue with the slas generating heat for the full burn time of the mlas for some reason?

Send in `a support ticket and see what they say.

If you time how long it takes to cool down to 0% it will be the same in both cases due to heat being generated over time and dissipation starting the moment you have heat, works like this with all lasers. So the moment you start to fire one it is dissipating so the end % when the beam stops is lower. If you fire more than one, the same amount is still being dissipated so it will appear to have a higher %.

For example with 10 shs (40 heat, 1 heat per second dissipation):
One ML fires and generates 4 heat (10%), but your dissipation is 1 hps, so over the beam duration 1 heat is dissipated so the end result is 7.5%.
When you fire 2 ML's you generate 8 heat (20%) but still only dissipate 1 heat in that 1 second beam duration, leaving 7 heat or 17.5%.
So one takes you to 7.5% and 2 takes you to 17.5%. The more you add the more it is noticeable, but you will hit 0 heat in the exact same time.

Note that small lasers have a shorter beam duration. Their heat is generated over a shorter period of time and therefore less dissipation has taken place at the moment you reach peak heat.

Assumptions: 20 double heat sinks (10 + 10), heat neutral map, standing still, basic efficiencies only

Case 1
Firing 2x ML
Heat capacity: 70.4
Heat dissipation: 3.66 / sec
Weapon heat: 2 * 4 = 8 heat over 1 sec
Peak heat value: 8 - 3.66 = 4.35
Peak heat percent: 4.35 * 100 / 70.4 = 6.17% (i.e. flashes 6% briefly then quickly drops to 5%)


Case 2
Firing 7x SL
Heat capacity: 70.4
Heat dissipation: 3.66 / sec
Weapon heat: 2 * 7 = 14 heat over 0.75 seconds
Peak heat value: 14 - 0.75 * 3.66 = 11.26
Peak heat percent: 11.26 * 100 / 70.4 = 15.99%

Test it on testing grounds using the minimum possible heat sinks so that the heat generated is a larger fraction of the total and you get better numbers.

You could also try firing all lasers as an alpha and see if there is a non-linear drop in heat at a particular number of lasers firing.

However, if the observations are correct it sounds like a bug and should be reported.
