How do I change the size of a sprite gradually ?

EDIT : Check the message under to understand my new problem, thanks

Hi ! I'm trying to do a plateform game, but here's my problem :

Before entering the pyramid (where all the levels will be in, like an intro), the player will be moving from the left to the right of the screen. I want to create a depth perception effect, for example the sprite initial size is 30x30 and as he goes further to the right, he'll end at a 5x5 size.

Here's a little drawing I did with paint to help you understand (check the attachment ) :

IMPORTANT DETAILS :

• If the player goes to the left, he gain size, like he becomes bigger going to the left and smaller to the right
• If he keeps going to the right, he can't be under X size, I don't want him to disappear (same for the left)
• The animation must be gradual and smooth, sexier
• I'll love for ever the person that will help me

Thanks

Actually nevermind, my friend managed to do it

I've put the how-to-do-it as an attachment

You can use linear interpolation functions to change the player's size based on thier X. Have a read up on lerp in the manual.

Player.Width = lerp(30, 5, Player.X/PyramidX)

Player.Height = lerp(30, 5, Player.X/PyramidX)

You can also affect the jump height and walking speed with the same function, to add to the illusion.

Oh thank you, I won't say no to more options

I have another problem though, before I did the change-size thing, I could have my mirror effect applied for when the Sprite was going to the left, now it's disabled so no mather what I press, it will always face the right and never turn, got any ideas on how to arrange that ?
