Scale Survival / Round Progress

Adjust respawns thoughout Survival match to open up a variety of play styles that can make Survival feel more like wave survival, randomized checkpoint, hunt, or survival with player respawns.

Why?

The issue with survival for me is that it provides little incentive to kill bots. They respawn faster than you can kill them and they don't decrease in count unless you set DPR high. This mod is meant to provide incentive to kill bots by providing a growing number of bots that respawn slower or a higher number of finite bots for 2 waves. This way players can keep up with the numbers and must to survive later in the round. Players will have to hold their ground to whittle down enemy forces and progress once bot levels are manageable. This is especially helpful with low player counts. An additional motivation is provided in FortuneSoldier, which rewards players with supply points for kills and allows more scavenging slots. 

Details

Survival gets insane with a quickly respawning bots and with player respawns gets very messy as bots will be swarming the respawn point. This is an alternative way of scaling difficulty that scales respawn time slowly throughout, while adding 2 waves of bots after each objective. This can be set alongside the vanilla bot increase on objective, and kept to a higher number of bots as they wont reach high numbers unless the players aren't killing them. Note that bots are respawned in a queue, so this time sets how fast the front bot in the queue will take to respawn, then the next one in the queue will also wait this time again and so on. If RespawnDelay is 10 and 5 bots are waiting to respawn, it will take 50 seconds to spawn them all. Setting this to something as high as 20 and you may never see some bots at all as the queue is paused whenever players are on objectives. The difference between each second in RespawnDelay is large.

Additionally, more flexibility is added with the ability to speed spawn amounts of bots in waves after captures. This way the RespawnDelay can be kept high to incentivize players to keep bot count down, while making sure that bot count is not zero. This provides more of a finite bot feel like checkpoint, but continuously grows if not addressed. More control is added with the option for random ratios to spawn after capture and a randomly occurring second wave sometime after an objective capture. Separate control over bot spawns is opened up for extraction as well for those that feel the chopper makes the final counterattack to easy. This can be set to add an additional wave and lower the respawn delay for bots during this period. Bot counts will still respawn up to what's allowed by the bot count set by MinimumEnemies and MaximumEnemies in Survival Settings. To avoid issues of player spawns getting swarmed, bSaveProgress can be used instead of player respawns, because with infinite bot counts a respawn is essentially a objective reset.

TLDR

By default, this mod slows spawns substantially and spawns bots in 2 waves after each objective. All variables are more or less one of three kinds:

RespawnDelay is the standard delay to respawn a single bot between objectives. 2 bots will take 2xRespawnDelay to spawn.
Ratios are for speed spawning a certain amount of bots at start, after objectives, or during extraciton.
RatioDelay is to set how long after events the ratio of bots will be spawned to enable players to loadup.

You can configure this in one of two ways:

1. Set bot count at ~20 and ratios at ~0.4 and respawnddelays to < 10 . This will make a slow decrease in bots with progression.

2. Set bot count very high at ~40 and set ratios ~0.8, but keep respawndelays very high > 15. This will make the progression impossible until bots are eliminated.

Bot respawn delay is found by the following algorithm:

TotalObjectives=NumWaves-1
BotRespawnDelay = StartRespawnDelay + (CompletedObjectives/TotalObjectives)*(FinalRespawnDelay-StartRespawnDelay)
