Everytime you hook a callback using the `hook` macro, the final name of the callback becomes `hook <callback>@<unique_id>`. Now everytime you include `y_hooks` it generates a new unique number to append to the final callback name. Now as you might be aware, you can not have callbacks/functions of the same name, this doesn't compile.



Now this is what is happening with your issue, you have included `y_hooks` and have hooked the same callback twice, without including `y_hooks` again after the first hook. So the unique generated ID, is the same for each hook, which is why it is not working here. So to fix this issue, include `y_hooks` before you hook the next callback.



So this code below is bad.

Code:

#include <YSI_Coding\y_hooks>



hook OnPlayerConnect(playerid) // Final Callback Name -> OnPlayerConnect@001(playerid)

{

? ?return 1;

}



// This causes an error due to having the same name

hook OnPlayerConnect(playerid) // Final Callback Name -> OnPlayerConnect@001(playerid)

{

? ?return 1;

}

This is the fixed version that allows you to hook the same callback again

Code:

#include <YSI_Coding\y_hooks>



hook OnPlayerConnect(playerid) // Final Callback Name -> OnPlayerConnect@001(playerid)

{

? ?return 1;

}



#include <YSI_Coding\y_hooks>



hook OnPlayerConnect(playerid) // Final Callback Name -> OnPlayerConnect@002(playerid)

{

? ?return 1;

}
