WaveSize Overview

From the post http://www.arcengames.com/forums/index.php/topic,6778.0.html

By X4000

Well... it's really, REALLY hard to describe in a concise way in terms of the wave size in particular. There are literally a few hundred lines of code in at least three files that govern this. Make that four files.

The basic underlying rules are thus, though:

1. Higher AI Progress leads to larger waves, pretty linearly. 2. Higher AI Difficulty levels lead to larger or smaller waves, not quite linearly. 3. Higher tech levels lead to corresponding drops in wave size (equivalent to the drop in ship cap at those tech levels). 4. The max/min time between waves varies by AI Difficulty level, and is randomized by around 30ish minutes or more (per AI). The wave size is 1x normal in the middle of that range, and is down to perhaps 0.4x at the lower end, and maybe 3x at the upper end. Or something along those lines.

The above governs all waves and their size, regardless of anything else. But on top of that, and where the biggest complexity comes from, is that there are an absolute ton of possible modifiers:

1. Ships with wave bonuses. 2. The actual end cap on wave size per line item (something like 2000). 3. The number of players in the game (it's 1 line item per human player or homeworld per AI, so 2 total in 1 player, 16 total in 8 player, with either 1 or 2 coming at a time in 1 player, and 8 or 16 coming at a time in 8 player). All the waves from a given AI go to the same planet in multiplayer games, so at most two planets are ever targeted at once. 4. The ship type in use (even in schizophrenic) causes a multiplier. You see fewer vampires always, but always way more laser gatlings. 5. Sometimes a starship or two are added in, but this sometimes costs the AI smaller ships from the wave (depends on the AI type). 6. Recently, same deal as #5 when it comes to "support ships" like munitions boosters and shield boosters, etc. 7. AI modifiers obviously can alter all this. 8. There are also variances per AI type. Mad Bombers have something like 3x larger waves, but almost no defenses, for example.


And... I think those are some other variances, but those are the high points. You won't ever be able to predict wave sizes, trust me. I coded almost all of the variables for it, and I'm not ever able to predict it. There are too many layers of variables and randomization on top of all that. Best advice is to keep the AI progress low and to avoid ships with wave modifiers, and that's mostly all that would be actionable data from all that in a given campaign.


Some other factors: AIs of difficulty 8 get one extra wave per wave instance. So in 1 player games that's 2 waves per AI, in 8 player games it's 9 waves per AI. On difficulty 9 it's 2 extra waves, and 10 3 extra waves.Verify

previously, there was an extra wave per wave event for difficulty 8, two extra waves for difficulty 9, and three extra waves for difficulty 10. This made the game WAY harder for solo play on those difficulties, but much easier the more players you have (since this didn't scale per the number of players). Now it has been changed so that there are no extra waves per wave event on difficulties 8 and 9 (as the more recent changes to wave sizing make this unneeded, anyway), and the number of waves per wave event is simply doubled on difficulty 10 (so that way it scales appropriately with the number of players). Normally there is one wave per home planet of the players per wave event. Thanks to Dazio for reporting. Warp Jammer Command Stations now block counterattack waves. Thanks to Winter Born for suggesting. Counterattack waves are now 4x larger than normal, but take a full 14 minutes to arrive. This makes them more of an event than they used to be, even, but also makes them much easier to prepare for and deal with
