Hi, I'd like to know how to fix env_spritetrail in L4D2.

I tested it by attaching it to func_rotating and the result is that it rotates once and then it disappears.

For CS:GO there was the same problem, which was fixed with [CS:GO] Spritetrail fix.

However, in L4D2 it is not working.
Is there a way at all?

Best regards.

Could you share the code snippet to help you better?

It will fully work in CS:S & CS:GO. However, the exact (changed) same method(s) will be used. The ideas was to fully support all SRCDS games which contain these 2 entities. I think it would be fun for people to have. However, I do not own all games, nor can I achieve everything. Greetings.

Nice work, it's indeed working (L4D2), the only downside is that seems that the func_rotation is following the player angles, don't know if this is intended nor is possible to make it in a fixed pos.

Hi,

I think it is because env_spritetrail is set parent with func_rotating and func_rotating is set parent with client.

env_spritetrail's lifetime may causing it.

I have tested it with a 0.1 sec timer and used TeleportEntity to client instead of SetParent. It just fixed the issue with when client looks up/down that the entities will do the same.

I really don't know, and I am far from being an expert.

Do you have any ideas?

https://developer.valvesoftware.com/...ing)#SetParent

Normally, you need little delay between SetParent -> SetParentAttachment (or SetParentAttachmentMaintainOffset)

Also, you need little delay when teleport entity to right place, before SetParent.

Use timers.

[Marttt]

The parenting actually works,
What I mean is that it follows the player's eyes' angles when it should be static.
I don't know going deep if when we attach it "chooses" the first attachment slot.

So for as I understood the problem, it is about the trails "expand in lenght" when player is walking. For that i do not know how to solve (if it is even solveable).

Now, for the problem where the trails change their origin when the player is looking up/down, i dont know how to fix it without using a timer teleporting the entities every 0.1 seconds.

¯\_(ツ)_/¯
