Customizable Blood System

Yeet!
Toss another realistic mechanic to the Workshop

Alright so, this is why I was away from publishing new addons for a while... and also cuz I got a little burnt out from modding, so I needed a break hehe.
But as always, here I'm back with another interesting mechanic :3


Well, to start, the title it's pretty self-explanatory but I'll go into details as I always do.


My thoughts for this mod were to add a new mechanic where survivors could loss blood, weaken if they blood levels are too low, and bleed out from untreated wounds without necessary being incapacitated. Cuz you know, you can be beaten multiple times and be so close to death, bleed for hours being incapacitated, get destroyed by a horde, a Charger or even a Hunter which has some VERY dangerous claws which can torn you apart in no time.
But the fact that you can easily forget about what just happened and continue with your journey by just using a first aid kit, it's a little unrealistic xD
But, first aid kits have no magic so your body will just give up from too many injuries over time if you keep pushing it's limit.

So, here I bring this script which it's job is to handle and manage all survivor blood levels and injuries throughout the entire campaign using several files and Cvars/Console commands to acomplish this.

At this point the mod description may seem like a little realistically overkill in terms of gameplay-balance, but it's not, don't worry. It is less noticeable in-game hehe
As long as you don't get incapacitated and beaten up constantly (?


This mod uses survivor_incap_health and survivor_incap_decay_rate Cvars/Console commands as a base. So keep that in mind if it doesn't work well on your game.

How are these variables used in the script?
Well, the script takes survivor_incap_health Cvar value (Which is 300 by default) and uses it as the starter and maximum blood amount a survivor could have. Then it uses survivor_incap_decay_rate Cvar value (Which in this case it's 3 by default) as the amount of blood a survivor loss per second by bleeding on the ground.
In other words, the script will behave accordingly with whatever value you are using on these 2 variables.

How is gameplay affected?
Survivors start a campaign as always, but this time having 2 new health related indicators, blood and wounds.
The Blood indicator (which was described above) it's strongly related with the Incapacitation state, this is because it's the easiest way of lossing blood and also because it affects the maximum health you get when you get incapacitated.
And the Wound indicator, which has no maximum and raises whenever you receive damage (As long as your true health is very low). It also raises by getting damaged while being incapacitated.

Now, let's go in deep with these indicators a bit and how they affect you.

Blood:
As you read above, survivors loss blood as they bleed while incapacitated, but also by dying. You can also loss blood by untreated wounds. If you have been incapacitated at least once and you haven't healed, you'll loss blood with some actions until wounds stop bleeding by themselves.
The way you regain blood is by healing, there is a small chance to restore a random amount of blood when you heal or someone heals you.
Blood affects your maximum health when you get incapacitated, so the more you get incapacitated the less you'll last. Having no blood will cause you to die right away if you get incapacitated.

Wounds:
Wounds affect your blood and health in general. As it says above too, survivors receive wounds by taking damage while in low health or being incapacitated. They also receive wounds by getting incapacitated by any means.
Wounds are also healed by a random amount (Twice than blood) with first aid kits, but instead of being a small percentage, they always heal wounds.
Untreated wounds make you loss blood the more actions you do. Being quiet while teammates protects you could be a way of losing less blood but still.
Having no blood but wounds will start to take your health slowly until wounds stop bleeding or you die.



Since this is my first script which uses ems to be able to customize it, here I leave all the settings and what they do:
You can find the mod files and setting by going to your game files --> left4dead2/ems

On Incap - Blood loss (Default: Off): This setting lets you edit the amount of blood you loss when you get incapacitated no matter the way.
Be aware that this setting lowers your blood after your health is applied. So this don't affect your incap health right away, only on future incapacitations.

On Incap - Add wounds (Default: 20): This setting lets you edit the amount of wounds received when you get incapacitated.

On Death - Blood loss (Default: 25): This sets the amount of blood a survivor loss upon death.

On Death - Add wounds (Default: 10): Same as last setting, but sets the amount of wounds received by dying.

On Bleed - Forgiveness (Default: Off): This setting affects the amount of blood a survivor loss while being incapacitated, so the number used here will make the bleeding less by the amount specified.
Example: If survivor_incap_decay_rate is 3, and you set this setting to 1, you'll loss 2 blood per second instead of 3.
This value can't be higher than survivor_incap_decay_rate, otherwise it will set itself to the same value to avoid problems but this will cause blood not being lost by incap bleedings.


This works better if you set the max incapacitation count above 2.
I also consider this the big brother of my Realistic Status On Low Health Revive script I uploaded a while ago now. So these two where meant to work perfectly together and you can also combine them with HexToMax's Customizable HP Regen Script.
Should not collide or cause any problems with any other health related scripts due to its adaptive behaviour. But this doesn't mean it's perfect, so if you find a problem or any incompatibility tell me in the comments and I'll keep that in mind.
