void HudResetState()

This is a HUD Library function.

Resets all HUD Library State to defaults. Should be used at the beginning of any drawing to clear any state left by previously run scripts, just like SetHudSize and SetFont are used for that purpose.

HudResetState();
HudSetPoint(320.0, 240.0);
HudDrawText(1, "Hello");

This function is not affected by current HUD Library state and doesn't overwrite it:

function DrawSomething(void)
{
    HudPushState();
    HudResetState();
    ...
    HudPopState();
}
