    0A8D: 12@ = readMem 11@ sz 4 vp 0
    0A8E: 11@ = 10@ + 0x6AE30 //SAMP_SET_DIALOG TEXT

Hello , i'm back.
Maybe somebody can explain how to know how many params need every time?
For example now i found pointers of Set chat input enabled , but when i call i get couple errors also my character was freezed , that means pointers are good, because i know when we open chat we can't move.
So problem is with call. I never know how many param need and how i should call it.

:SET_CHAT_INPUT_ENABLED
{
    0.3.DL
    0AB1: @SET_CHAT_INPUT_ENABLED 1 status 1 // 0 = CLOSED , 1 = OPENNED
}
IF 0AA2: 10@ = "samp.dll"
THEN
    0A8E: 11@ = 10@ + 0x2ACA14 // SAMP_CHAT_INPUT_INFO_OFFSET
    0A8D: 12@ = readMem 11@ sz 4 vp 0
    0A8E: 11@ = 10@ + 0xA0530 //SAMP_CHAT_INPUT_OPEN
    0AA8: call_function_method 11@ struct 12@ num_params 1 pop 0 0@ 1@
END
0AB2: 0

Open IDA, rebase the program to 0x0 and travel to offset 0xA0530. Check the psuedocode for params, calling convention, and use xrefs to see how samp.dll is calling that function. I'm not saying you should rely on psuedocode, but it should be enough for this function.

I never use before IDA.
I try , thx.
