Title: Animated Wackiness
Post by: Jarwulf on September 30, 2009, 01:30:06 am

I used Hiura's Animated Class with good results. But there is a hiccup when I try to place it into one of my classes. I have a class called wanderbot which has Animated BotImage as a member.

BotImage works fine when it is declared in main() but if I put it in wanderbot and put  

Code: [Select]

Basicbot.BotImage(botgo[UP],0.1f);

to start the animation in main it says.

Code: [Select]

term does not evaluate to a function taking two arguments.


I can take out the code and it compiles fine but the bot animation is jiggling and blurry.

Can I show the minimal code source that reproduce the problem ? ( I've never saw this. )

My code is too messy and huge to post but here's a skeleton of the problem.

Code: [Select]

class Wanderbot//Class defining Bot behavior
{
 
       public:  
 

          Animated BotImage;
         int loadimage;


 void alertstatus()
{
if (loadimage==0)
{


      BotImage(botgo[UP],0.1f);
   
      BotImage.SetPosition(500.f, 50.f);
     //animation of bot
        }
}
};




In your code you use

Code: [Select]

 
    Animated boy(go[UP], 0.1f);
 

to set boy's initial direction. When I do the same its fine but if I move my Animated BotImage into a class as you see above the compiler complains. I think because it believes Animated BotImage and BotImage() are two different things. The bot moves around but it jiggles a lot .

You can't call a constructor like this -- a constructor is only called when an object is constructed ;)

1. First solution: use the initialization list, which is the only place where you can call your member's constructor

Code: [Select]

Wanderbot::Wanderbot() : BotImage(botgo[UP], 0.1f)
{
    ...
}

2. Second solution: if the Animated class is copyable and assignable, you can assign your object a copy of a new instance

Code: [Select]

BotImage = Animated(botgo[UP], 0.1f);

3. Third solution: add an initialization function to the Animated class

Code: [Select]

BotImage.initialize(botgo[UP], 0.1f);

#1 and #2 will work fine.
You can also do this :

Code: [Select]

BotImage.SetAnim(botgo[UP]);
BotImage.SetFrameTime(0.1f);
BotImage.SetPosition(500.f, 50.f);
