System / Only want a function to get called once on a keyDown.

« on: January 24, 2012, 08:51:07 pm »

sf::Event does seem the best way to do this. However, it seems that I cannot pass my window instance to my class. Any idea's how to use sf::Event within my class?

I want to do something every time the button is pressed.

Can anyone lend a hand on this? I'm struggling to get this working.

I'm using this

this->LeftButton = sf::Keyboard::IsKeyPressed(sf::Keyboard::A);
if( this->LeftButton ){
      this->MoveLeft();
   }

Hello, I'm using AniSprite to animate my sprites, this works well and I can play animation with ease.

When I press D on my keyboard I'm adding some velocity to move my sprite, but at the same time I'm calling AniSprite.Play(0,5); to play the animation. The obvious issue here is that Play(0,5) is called every frame, so that the animation never actually starts.

How do people get around this?

System / Do something every 10 frames

Yeah 2.0 and yeah I figured that soon after I posted this!

Hay, I'm using window.GetElapsedTime() to keep my framerate consistent across multiple computers.

How would I use this to see if 10 frames have passed? So every 10 frames do something?

Graphics / Is it possible to draw FloatRects to the screen?

I guess that's the only way to do it. Ok, thanks.

but RectangleShape doesn't have the methods like Intersect and Contains though.

As the title suggests, I'm using FloatRects for some collision detection. Is it possible to draw these to the screen so I can see their positions? I know I could simple copy the attributes of said FlaotRect then create a Shape, but I'm wondering if it's possible without the need of using Shape.

Thanks!

Graphics / Jump doesn't realistically

How would I about doing this? If Y is above a certain point then change the yVelocity, or if a certin amount of time has pass changed the Yvelocity?

Hay I have a simple script which makes my sprite jump.

I have this line being fired every frame

   this->sprite.Move( (this->deltaTime * this->xVelocity), (this->jumpSpeed * this->deltaTime) * this->yVelocity);

And when my jump button is pressed this code gets run

this->yVelocity = -this->weight;
      if (this->sprite.GetPosition().y < apex) {
         this->isJumping = false;
      }

This works well. I hit jump, my character jumps, reaches a peak then drops down. However, my movement is more like an upside down V rather than an arch. How would I accomplish a more "real" jump effect?

Are you playing the animation? Do you have any code to show us?

Hmmm, ok I got it all working apart from the clock.

I get these issues

Code: [Select]

Undefined symbols:
  "sf::Clock::GetElapsedTime() const", referenced from:
      AniSprite::Update()     in AniSprite.o
  "sf::Clock::Clock()", referenced from:
      AniSprite::AniSprite(sf::Texture const&, int, int)in AniSprite.o

  "sf::Clock::Reset()", referenced from:
      AniSprite::Play(int, int)in AniSprite.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

But the clock is setup in the head file? Any ideas?

Care to explain how you got it working?
