Captcha Effect

Question

out of curiosity what is the thing that spawns this shape on the ground? as you can see they are symmetrical and the lines are perfectly straight

also it seems to be 2-3 'clicks' stacked on top of each other too

 

what packet/method is being sent to spawn this effect? i don't think their devs are that advanced to create a new abnormal effect so i will rule that out 

can something similar be done using a similar idea?

I doubt it's retail, so it's probably a custom AbnormalEffect using mouse graphics.

 

Without any client edit, you can use ExServerPrimitive to draw Lines and Points (and by extension, any form you want). Here's an exemple used for movement debug purposes.

 

You can eventually use L2PHX on the server and see which packet is actually sent when captcha occurs.

@Tryskell i saw this effects 10 years ago on the Lineage 2 Epilogue L2J project. This effect used for showing pathway to selected Private Shop from Item Broker in all tradable towns. This effect dissarpes after some time itself.

 

Possible for IL client is not valid, but for highers it's feature. Anyway at this moment for me unknown what the packet was used.

ExShowTrace then.

@Tryskell yes. Found leaked sources with Item Broker and this script uses this packet.

Can be used for any clients starts with Kamael.

if u want to make the same captcha yourself, add randomization of points amount and rotation of whole figure, to make it a bit harder.

 

I wanted to do something similar or with abnormal, and to have different tasks (random one each time) when you get reported. I understand 90% of players need to use bot but I don't want people botting entire day. They can bot if they are on pc and watching.

 

Can add stormfrontboosting on Skype and maybe we can talk about possible solutions
