Hook into GuiCrossHairHud

by gamer · in Torque Game Engine · 04/03/2006 (5:49 pm) · 6 replies

Hi,
in the fps, I want to be able to popup a hud on the side that displays some info when the aiplayer enters my crosshair. how can this be done? I know that GuiCrossHairHud displays a small damage bar when someone enters the crosshair, but I can't find an easy way to make a callback function and pass it to GuiCrossHairHud.
any ideas?
thanks for the help

The function you seek is
Con::executef(this,2,"onFunctionName",scriptThis());

placing it in the onRender would have it callback A LOT so where it is called is important

Excuse my ignorance, does this do the following?
when FunctionName() is called, then scriptThis() is called.
is this right?
thanks

It would callback to GuiCrossHairHud::functionName(%this) {}

Ok I tried a variant Con::executef(1,"scriptThis()"); in GuiCrossHairHud, but at runtime it says scripThis() command not found. I defined
function scriptThis(){
echo("hi");
}
what am I missing?
thanks

I also tried
Con::executef(this,2,onRender,"scriptThis()"); in GuiCrossHairHud.cc,
at runtime it gives this error:
Con::execute - 0 has no namespace: onRender,
what does this mean?

ScriptThis() is Method of SceneObject that returns the script representation of that object so you can access it in script.

Anothony's example is correct except for a small oversight. He forgot the on in the script function:

Con::executef( this, 2, "onFunctionName", scriptThis() );

would call this is script:

GuiCrossHairHud::onFunctionName( %this ) {}
