Tween sprite without changing its hitbox (arcade physics)

[Cawrtz]

Hi

 

I would like to tween my sprite when it falls on a platform to make it look like a slime (increase its width and decrease its height, then back to normal).

The problem is that I've enabled Arcade physics on it, and the body (body.width, body.height) is always adjusting to its visual size (sprite properties .width and .height).

game.add.tween(this).to({     width: currentWidth + 10,     height: currentHeight - 10}.onComplete.add(tweenBackToNormalSize);

That creates opportunities to glitch underneath platforms and many other unwanted side effects.

 

Is there a way I can get this effect without changing the hitbox ?

 

Thanks in advance!

Yann

What happens if you tween the scale.x/y, instead? I *believe* that just changes the texture, not the physics properties.

Hi drhayes, thanks for your answer!

I used scale instead of my width and height calculations

Unfortunately, it stills affects the physics body...

 

Maybe I could use another (visible) sprite that follows the (hidden) sprite body to bypass the issue?

Ah, shoot. I had high hopes for that answer. ( =

 

You might be right -- there's the sprite and its body and the sprite has a child image or something.
