Change Map Image on existing map?

[Charles Darwin 10]

In ArmA 1 days I played on a mission where when a player opened the map it showed a custom image instead of the standard ArmA map I am sure its possible in ArmA 2 just not sure how or what the name of that mission was to find out how he did it

Block the actionkey for the map with a key eventhandler and show a custom picture resource or a dialog instead.

Mid level scripted here so how would that on script?

So I popped open the ACE pbo that controls their map replacement and lost feeling on my left side, so stopped trying to understand it. :)

What is the name of that PRO

This is not my area at all I have only dabbled in it. Here is some stuff for you to digest and an example of something similar from an addon called "Mouse Wheel View Distance".

AddEventHandler

User_Interface_Event_Handlers

DIK_KeyCodes

This is not mine but this is an example of a displayEventHandler.

This is not my code! I am posting it as an example. It is from this addon.

// Change viewdistance with mousewheel tpw 20110214

hintsilent "Mouse Wheel View Distance 1.02 Active";



mwvd_min = _this select 0; // minimum draw distance
mwvd_max = _this select 1; // maximum draw distance
mwvd_inc = _this select 2; // increment draw distance
mwvd_hint = false;

while {mwvd_min > 0} do {
waituntil {mwvd_hint};

};
