if i want to resize a entity's size by it's 80%,what i should do?

Depending on what you're going for...

var factor = 0.8;

// Increase size by 80%
this.size.x += this.size.x * factor;
this.size.y += this.size.y * factor;

// Or...

// Resize to 80% of original size.
this.size.x = this.size.x * factor;
this.size.y = this.size.y * factor;

I wrote a blog post about doing this a while ago. Haven't done it in a while, but should still be relevant with newer Impact versions (I would assume):

(Edit: wow, I just noticed this thread is a year old.)

Yeah there seems to be some spam of people not reading questions and just promoting their tools by the looks of it and it's bumping old posts to the top
