RE: Gui problem
Try: if(exit)exit=0;
But you lose your pointer to exit button!!!

RE: Gui problem
This code should exit application? Maybe try if(exit)return false; or Exit() function.

RE: Gui problem
Not sure exactly what you are after with that button function... but... couple things wrong with it like others have pointed out:

A) its a void function - you cant return a value... ie: false.. only "return" to exit the function

B) exit is defined as a pointer to a button.. you are trying to assign a value of "return false" to it... that is just.. wrong smile

If you want to create a button that causes Esenthel to close... you could do this:
most tutorials have something like this in the Main ( recently renamed to Update) function:

if(Kb.bp(KB_ESC))return false;

That works becuase return false from the Update function causes the application to shutdown...

So.. you could do something like:

Create a global value called 'engineRunning'

Bool engineRunning;

in.. say the InitPre function.. set it to true ( defaults to true.. but.. I always like to make sure!)

engineRunning = true;

then... change "if(Kb.bp(KB_ESC))return false;" to :

if ( !engineRunning || Kb.bp(KB_ESC) ) return false;

then... in your ButtonFucntion...

engineRunning = false;


That'll make is so the either pressing escape or clicking your button will clsoe Esenthel... ( and still call the Shutdown functions and such for engine cleanup )

If you just terminate the application via Exit() or something else.. you will leave memory allocated in the engine.. which causes Bad Things ™
