scripted drawmethod disabled drawmethod frame commands/solved

[ABK]

Is it only me or this is well known? Ive got this script, and once it hits enemy then his drawmehod commands in pain attacks (tinting to red or white) dont work at all

			@script
                void self = getlocalvar("self");
                  void opp = getentityproperty(self, "opponent");
               if (  frame == 1  ) {
 changeentityproperty(self,"parent",opp);

   changedrawmethod(opp,"enabled",1);
   changedrawmethod(opp, "tintmode", 1);
    changedrawmethod(opp, "tintcolor", rgbcolor(100,100,200));
        changeentityproperty(self, "velocity", 0,0,0);
           changeentityproperty(self, "speed", 0);
      setentityvar(opp, "posx", getentityproperty(opp, "x"));
		}

		if (  frame == 40  ) {
               changedrawmethod(opp, "tintcolor", rgbcolor(0,0,0));
  		}

	@end_script

Or am i doing something wrong ?

Yes i did something wrong, if i use  changedrawmethod(opp,"enabled",0); then drawmethod commands work fine.
