IOS 2D Game Development Framework spritekit--> (Create User Role Wizard-original)

First, the main realization
Today Spritekit implements the creation of the Player Character wizard (Skspritenode *), which increases the gesture action of the character Sprite, and the added gesture calculation method is not the same as in Objective-c. Because the coordinate system used by OBJECTIVE-C is not the same as the coordinate system used by Spritekit, the wizard's collision check code is added later.

Second, Skspritenode gestures

The Skspritenode class comes with 5 gesture monitoring methods,

       
    1,-(void) Touchesbegan: (Nsset<uitouch *> *) touches withevent: (Uievent *) event
  
     Call when the finger moves
  
    2,   -(VOID) touchesmoved: (Nsset<uitouch *> *) touches withevent: (Uievent *) Event

    Call when the finger is lifted

3,-(void) touchesended: (Nsset<uitouch *> *) touches withevent: (Uievent *) event

      Cancel (abnormal leave screen, unexpected interrupt event)

         4,-(void) touchescancelled: (Nsset<uitouch *> *) touches withevent: (Uievent *) event

  3D Touch Correlation method, the current touch object estimates the touching characteristics, the return value is Uitouchpropertyie,

   5,-(void) touchesestimatedpropertiesupdated: (Nsset *) touches

6. The above 5 methods used most is 1, 2, 3, the following we want to manipulate the role of the wizard is also used to these three gestures, the realization of the idea → when the user clicks the screen to enter the 1 gesture, judge the point of the click of the coordinates is not on the Role wizard, if you can perform 2 gestures, The code with an int variable record, if clicked on the character Elf Int=1,int=1 2 gesture to execute, when the user hand lift, will be executed gesture 3, indicating the end of the gesture, we will set int=1 = 0.

Second, the Code

1. Add the code to create the role wizard in the scene layer initialization: Skspritenode * Firendplane

1UIImage *roleplaneimage=[uiimage imagenamed:@"Attackplane"];2Sktexture *roleplaneimagetextture =[Sktexture texturewithimage:roleplaneimage];3Firendplane=[skspritenode spritenodewithtexture:roleplaneimagetextture Size:cgsizemake (DEVICE_Width*0.25, device_width*0.25)];4Firendplane.physicsbody =[Skphysicsbody bodyWithRectangleOfSize:FirendPlane.size];5             /*Increased collision Monitoring Code*/6FirendPlane.physicsBody.categoryBitMask =Skrolecategoryfoeplane;7firendplane.zposition=1;8Firendplane.position=cgpointmake (self.frame.size.width/2, - );9[Self addchild:firendplane];

2. Add gestures

1-(void) Touchesbegan: (Nsset<uitouch *> *) touches withevent: (Uievent *)Event2 {3Uitouch *touctobj =[touches anyobject];4     5Cgpoint location=[Touctobj locationinnode:self];6     7     8CGFloat currenttagareax=firendplane.position.x-firendplane.size.width/2;9     TenCGFloat currenttagareay=firendplane.position.y-firendplane.size.height/2; One     if(Location.x>=currenttagareax &&location.x<=firendplane.position.x+ (FirendPlane.size.width/2) && ALocation.y>=currenttagareay &&location.y<=firendplane.position.y+ (FirendPlane.size.height/2)) { -          -Isornotachmyplane=1; the     } -      - } -  +- (void) touchesended: (Nsset<uitouch *> *) touches withevent: (Uievent *)Event - { +Isornotachmyplane=0; A      at } -  --(void) touchesmoved: (Nsset<uitouch *> *) touches withevent: (Uievent *)Event - { -     if(isornotachmyplane>0) { -Uitouch *touctobj =[touches anyobject]; inCgpoint location=[Touctobj locationinnode:self]; -          to          +         if(Location.x >= self.size.width-(FirendPlane.size.width/2)) { -              thelocation.x = Self.size.width-(FirendPlane.size.width/2); *              $}Else if(location.x <= (FirendPlane.size.width/2)) {Panax Notoginseng              -Location.x =firendplane.position.x; the              +         } A          the          +         if(Location.y >= self.size.height-(FirendPlane.size.height/2)) { -              $LOCATION.Y = Self.size.height-(FirendPlane.size.height/2); $              -              -              the}Else if(LOCATION.Y <= (FirendPlane.size.height/2)) { -             WuyiLOCATION.Y =FIRENDPLANE.POSITION.Y; the              -         } Wu          -Skaction *action = [Skaction moveto:cgpointmake (Location.x, LOCATION.Y) Duration:0]; About          $ [Firendplane runaction:action]; -     } -
