AS for making an MC bigger?

is there any kind of as that will make an MC bigger. like +10 width and +10 hieght. even better, is there any that will make it 2% or 5% bigger?

_yscale and _xscale

ohh, ok. so i would do _xscale = +5%?

i dunno about the percent, but _yscale+= 10; or whatever number you want until you get it to the right size
