ios - creating walls for simple maze game -


i doing single view game demo, maze game walls. player control character uibutton.

basically have devised need check if in next step, character going intersect wall, character movement return false. but, cannot seem put them together.

i have boolean function check if character going intersect wall

-(boolean) checkcollision : (cgrect) newframe{ cgrect frame = self.mainchar.frame; frame.origin.x = self.currentpoint.x; frame.origin.y = self.currentpoint.y;  (uiimageview *image in self.hardwalls) {      if (cgrectintersectsrect(frame, image.frame)) {         return true;     } } return false;

}

my uibutton movement is

-(ibaction)charmovingleft:(id)sender; { cgpointmake(mainchar.center.x -charmovement, mainchar.center.y);

what should adding button method stop movement when intersection going happen?

thanks in advance

-(ibaction)charmovingleft:(id)sender {      cgrect newframe = your_characters_frame_if_it_moved;      if (![self checkcollision:newframe];         //move character:      }      else          //dont move character }

will ... ?
