[L4D2] Survivor Set Flow Fix (August 30th, 2023)
 

Survivor Set Flow Fix
This plugin fixes oddities when playing with an unintended survivor set in campaigns.

This plugin fixes the following:

• Custom maps often detect which survivor triggered some button or sequence to play certain conversation lines, however in many custom maps important events are bound by these conversations happening so if, for example, Nick activates a radio on a map with the L4D1 survivor set, the map would softlock because the entity flow never considered Nick. The fix is done by manipulating the filter_activator_model's logic (the entity used most of the time to check the survivor), so it would also fix problems if your server has custom models.
• If a campaign sequence has a func_orator entity managing survivor conversations, whenever an unintended survivor activates it, it would keep playing conversations as if the event would never had happened. For example: Survivors keep telling to turn off the alarm in the second map of The Parish, or most radios keep asking if there's anyone alive when activated (All official campaigns).

Note that if your server has survivors with the m_survivorCharacter value higher than 7, they will be considered as Nick/Bill.

Download from AlliedModders:

You may need to download the .sp file and compile the plugin yourself if AlliedModders forum compiler lacks the necessary includes to provide you with a working binary.

You'll need to add a compiled version to the OP because the auto compiler doesn't have DHooks.

Odd, thought they changed policies on that a while ago because people were uploading both the compiled version alongside the source. Thanks anyways and I'll just have to do it locally :)

I think it has changed, you can upload a compiled version, we have Lysis to reverse the binary and compare with the source. Still recommend locally compiling from unknown authors or those without a reputation.

Does not work with custom models.

Re: [L4D2] Trigger Flow Fix
 

Can you give more context? This plugin was tested extensively on a heavily modded server, including survivors with custom models.

In case your server modifies the m_survivorCharacter prop of the player, the action would default to Nick/Bill.

Re: [L4D2] Trigger Flow Fix
 

I have rebuilt models on the server and my own plugin to select them. On the map "Death Toll" I start the radio, while I have a custom model (based on the l4d2 set). The radio continues to speak after the ending trigger is triggered.

Re: [L4D2] Trigger Flow Fix
 

hmm... I was led to believe it would be fixed but turns out this wouldn't fix this issue in official maps because those use func_orator as a way to determine the proper response. I'm updating the OP to avoid further confusion.

For me to fix this specific issue I need a way of hooking entity inputs since I needed to change the m_survivorCharacter value of the player on SpeakResponseConcept.

Excellent. We are waiting for corrections. I hope everything works out for you. A very useful plugin.
