What's the performance diff between 'Grenade' and 'Bullet'?

[TheJamsh]

Simply put, am I going to notice a performance difference changing bullet to grenade classes?

What's the extra overhead required to calculate the gravity influence on the ordnance? Is it going to be a huge performance impact?

[MrTwosheds]

Changing ordnance from bullet to grenade and having it perform like a bullet would create a weapon with a huge range, this would radically alter the "balance" of the weapon, eg destroy your enemy safely from 600 meters away behind your own defences by raining sp stabs on their base. There would be very little they could do to stop it.
Other than that I don't think there is much of a performance issue, unless you have done something inefficient to the effects.
Need to make sure you don't put any effects that emit ever increasing numbers of sprites, like the old plasma stream used to.

would depend on the weapon.
for max ordence at once bullets are better.
for more control over ordence use grenade.
I am sure it takes more to calculate the gravity influence on the ordnance [found out testing my thunder storm 1000+ordence] the bullets would run 2 as fast but don't arc so to keep the effect I droped the number of ordence and use grenades.

if your planning on changing the stock weapons a littel it should be fine if your making some new render happy monster all I can say is test the hell out of it and good luck.

The range isn't the issue, I'm using it on (strangely enough) the scion plasmas weapon to give it a slightly arcing effect like a flamethrower. The only issue I can see here, is that that thing generates ordnance every 0.02 seconds, which all individually have a lifespan of 0.8 seconds, so that's 40 grenade ordnances' spewing out of one unit when it uses this weapon.

(Also, I do use Grenade physics on the SP-Stab and AT-Stab, they have the same range as before, grenades respect the lifeTime flag too )

Plasma would tend to go up because it is a very hot gas.

[Nielk1]

Plasma isn't a gas at all...

[Ded10c]

Plasma isn't a gas at all...

That. Methinks twosheds needs to research states of matter

Plasma is comparable to gas, yes, but you can have plasma at subzero temperatures. In short, the defining factor is that it is ionised.

[Red Spot]

In physics and chemistry, plasma is a state of matter similar to gas in which a certain portion of the particles are ionized.

Lots ... and lots of people refer to it as ionized gas, saves a few words ..

[Ded10c]

When saving a few words makes you entirely wrong, it's not worth doing.

[MrTwosheds]

I didn't really want to start a physics discussion. Does anyone know wether a plasma, the hot kind, would go up, down or in a straight line, in an atmosphere or vacuum? Seems to me its just fine how it was anyway.

[Red Devil]

*checks plasma stream*

goes straight out and dissipates

[Ded10c]

Plasma that is hotter than the atmosphere, like in any other state of matter, will convect upwards. Convection won't occur in a vacuum.

[Red Devil]

so, if you shot some on Mercury or Venus, it might convect down. hmmm, planet-specific weapons...

maybe Mercurial Plasma Grenade?

Venusian Droopy Plasma Stream?

[Ded10c]

Density comes into play as well, of course.

[jaydenbz2]

Is it even possible to make the plasma goes upwards?
