Engine question: Intercept messages

How to Intercept Text Messages usually shown top left ?

Related to MessageListClass ?

Will it be something like TSPaintTextMessage() and it needs be detoured?

Looking for clues at:
tspp_audio_intercept.cpp
tspp_definitions.cpp

Hi there!

I'm not quite sure I understand your question, are you interested in how to display a custom message to the top left of the screen? (which you correctly identified uses MessageListClass).

MessageListClass::Draw will pickup and render pending messages to the screen. If you wish to have them draw elsewhere, you would need to either modify the MessageX and MessageY values of the class, or completely reimplement that function to perform the desired drawing style.

Code:

   // 0064D17E 8B 56 30 mov edx,dword ptr [esi+30h]
   // ugh. can we deny the string?
   // 0024D17E
   // 0064D17E 8B 56 04 mov edx,dword ptr [esi+04h]

0x0064D187 call Simple_Text_Print $ADDRESS ESI {(char**)(esi + 0x30)}

0x0064D187 call Simple_Text_Print 0x0064D187 ESI 0x281606b0 {0x007e2db8 "OBEY. CONSUME. CONFORM."}
