PLEASE HELP ME IM USING TFS CRYING DAMSON 0.3.6

 

[Pyromaniack]

Anyone?

 

[Cykotitan]

1213004 is the only way

 

[YugiNao]

1213004 is the only way

and how can i fix npcs for normal mystic spirit? i got premium, but whenever i download a tfs 0.4 and convert the map it says FATAL Unable to load otbm file blablabla xD,
Thats why i use mystic spirit how can i fix this that npcs just talk in NPC channel, ive searched everywhere tried everything and couldnt fix it.. i tried otland.net / google.com and otfans.net T_T nothing that actually works or is compatible XD

Ok, so how can i make the npc answer me in 0.3.6 8.70? CYKOTITAN plx answer me =*

 

[YugiNao]

i think copy the right distro and transfer all NPC lib folder to your distro..

and i found a solution.. butt that means that we have to change everything T_T ,

solution NPC channel

npcHandler:say('How can i help you?', cid)

That means.. we gotta adjust all scripts and we need lua scripts for item npcs.. to make it sellable if you want to use PRIVATE T_T

 

[Pyromaniack]
