any help ?

i make it in a different files

client.lua

clinet1.lua

client2.lua

with a timer for client1 and client2

client :

txd1 = engineLoadTXD ( "sniper.txd" )

but still gives me crash

Check returned value all functions.

Also, try replace other model.

it will works if i leave the first client , maybe i should make other scripts for other models?

yes thank you for helping me the problem was this model :

txd16 = engineLoadTXD ( "tec9.txd" ) 
engineImportTXD ( txd16, 372 ) 
dff16 = engineLoadDFF ( "tec9.dff", 372 ) 
engineReplaceModel ( dff16, 372 )
