Trying to improve armor glow effect

Posted on July 4, 2009

Several people commented on the armor ‘glow’ effect to represent an armor hit, but not hull damage or a shield hit. Ideally the effect says “this hit the ship and got through shields, but it didn’t get any further’. my plan was for the ship to look like it ‘glowed’.
The problem was, that with the whole ship glowing, it looked a bit overdone, and non-specific. After a lot of fiddling, I can apply an expanding and fading sprite as a ‘decal’ to the ship (which is fiddly without assuming shader support, and involves some interesting multi-texturing code and so on…)
Here it is: ( i stupidly called it shield effect test. it’s armor effect. doh!)

Is this better? If not, what would work better?
Cheers!

New video at last

I bought some proper editing software for videos (Sony Vegas Movie studio only £40) and spent all of today learning it and getting this made:

Let me know what you think so far.

Cheers!

Lightning!

Posted on July 2, 2009

I’ve been tweaking and fixing a few small things lately, sounds that do not play, some graphical problems, and some bugs caused by recently introduced new features (I managed to screw up the way shields worked when I added cod to make ‘stacked’ shields less effective.

In amongst this, the only true ‘new’ feature that has gone in is the alliance ‘lightning gun’. It’s basically just a beam laser, but drawn entirely differently. 10 minutes of reading photoshop tutorials got me up to speed with rendering lightning, and then a bunch of rendered strips of lightning later, I wrote code which works out how many ‘chunks fit in a beam, and stuck together a string of them so the ship looks like its electrocuting its enemies.

The code isn’t that simple, because you want the beam to zig zag everywherem, but hit its origin and target exactly, which is a bit fiddly. I also had it change which bits of lightning to use every 10th of a second so it looks like it flickers, and had to ensure that multiple beams from the same ship start at different points so you can’t tell the same texture pattern was being used.

Having said all this, the biggest effort was picking out a sound effect for it, which I’m still not happy with and am not confident is playing right. 30 minutes of previewing sounds of electrical static is a bit wearisome in 86 degrees in the indoors with an overheating PC by your legs.

All good fun I guess.

How shields do (and will) work

Posted on June 28, 2009

Every space movie has deflector shields, and so does GSB. here is the current system:

You can optionally add shield generators to your ships. The more the merrier, and some provide more shield points than others. The total shield points get added together as the shield strength. This strength needs top be blasted to zero to knock out the shields. In this respect, all generators act as a linked unit.

3% of weapon hits somehow luckily get through the shields anyway (luke skywalker lucky shots)

Shields have strength, but also resistance, and weapons have shield damage, and shield penetration. If shield resistance > shield penetration, the weapon is totally ineffectual. Otherwise, shield damage is applied to shield strength

Shields recharge over time. You need to totally blast a ships shield strength to zero to stop it recharging.

Now for the new bit (working on it now…)

Shields will have ‘stability’ which indicates the integrity of the energy field. Special weapons (probably torpedoes) will be able to interfere with the stability. If the stability is reduced to zero, the shields will temporarily collapse, effectively turning them off and allowing weapons to penetrate. These shield disruptor weapons will ignore shield strength and resistance, working on totally different principles. The only defence against them will be point defence lasers and ECM beams to scramble the torpedoes.

This way I’m avoiding the possibility of just havign seriously ‘shielded-up’ ships that are effectively impossible for enemy ships to overcome. Another possibility I’m toying with is preventing shield generator modules from being 100% additive, but maybe on a sliding scale.

So 1 shield module = 100% of its strength, 2nd shield module adds 80% of its strength, etc etc.

Thoughts?
