[SCRIPT] Trying to break a breakable box with a crowbar

[TheCyberToad]

Was trying to make a breaking script

Code: (Select All)

void OnStart()
    {
void AddUseItemCallback("", "crowbar", "healbox_1", "BreakBox", true);

}

void BreakBox(string& asName, string& asEntity);

{
SetPropHealth("healbox_1", "0");
}

 but it says the open token is unexpected.

Code: (Select All)

FATAL ERROR: Could not load script file
'custom_stories/labstory/maps/00_scripttest.hps'!
main (12,1): ERR : Unexpected token ‘{'

The healbox_1 is a common wood_box02_breakable.ent.

Are there any more proper ways of doing this if it's too wrong?
