python - When I try to add an argument to one class I get a Typeerror for classes that inherint from another one -

-

I have received this code and there is no error in it: 

  class weapon ( Object): # No know that it can be successor (object) def (__int __ (self, weapon): self.weaponName = weaponName class character (object): def __init __ (self, name, weapon name): self .name = name self.weapon = weapon (weapon name) class NPC (character): def __init __ (self, name, weapon name): super () .__ init __ (name, weapon) class friendly (NPC): def __init __ (Self (Name, weapon name) sword = weapon ('sword') guard = npc ('bob', 'sword') print (guard.weapon.weaponName) print (): (name, weapon name): super () .__ init __ Guard.name)   
 But when I try to add a loss feature in the weapon class:  
  class weapon (object): def __init __ (Self, weapon, arms, damages): self.weaponName = WeaponName self.weaponDamage = weaponDamage class character (object): def __init__ (self, name, weaponName): self.name = name self.weapon = weapon (weapon name) class NPC (Charit ): Def __init __ (self, name E, weaponName): super () .__ init __ (name, weapon name) class friendly (NPC): def __init __ (self, name, weapon name): super () .__ Init __ (name, weaponName) sword = weapon ('sword', 15) guard = npc ('bob', 'sword') print (guard.weapon.weaponName) print (guard.name)   
 I am getting:  
  traceback (most recent call final): file "D: \ Python files \ legacy test.py", line 21, & lt; Module & gt; Guard = NPC ('Bob', 'Sword') file "D: \ Python Files \ Legacy test.py", line 13, __init__ in Super () .__ init __ (name, weaponName) file "D: \ Python Files \ Legacy "  
 Why is that so? I do not want to refer to asphalt anywhere in character character, I want to use it in later work such as attacks and if I have many weapons I would like to be able to say that 'this example of friendship There are X weapons' and from there it shows that the loss of weapon is due to seeing the exemplary example of the weapon class.   
 
 
 You asked:  
 
 Why is that so?   
 You specified in the  weapon .__ init __ ()  that it requires the  weaponDamage  as an argument. If you make an example of  weapon  anywhere, then you have to give value to the  command command .  
 You can correct the error by providing a default value for  weapon command .__ init _ () .  
  class weapon (object): def __init __ (self, weapon name, weapon = 0): self.weaponName = weaponName self.weaponDamage = weaponDamage

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
