A few questions about sprite and map properties

[purplecyty]

Ok so far I am working on a game in rmxp and its pretty easy to figure out what I mean but I just wont quite give away its purpose yet -.- anyways I did a edit to line 51 of the sprite character script and this is what I did

         self.zoom_x = 8
        self.zoom_y = 8

And i will like to know how I will get it to make sprites look 8 times as big when they are the lowest to the screen and when they are the highest they should be about 2. I tried making
self.zoom_x = @character.screen_y*(-1)/10
so that it would appear bigger the less the screen y was but it stayed the same size no matter what. I would like some help to making the zoom greater when it is closer to the bottom -.-. Also I would like to know how I can make the tilest zoom. i tried to add in line 119 a
@tilemap.zoom_x = 8
but it says it wasnt recognized
one other thing and thats I want it so when my characters are zoomed that if you touch them even at the upper half where it doesnt regist them to be, that it will register them. Normally it just registers 1 square where their feet is to be where they are, therefore they can easily overlap each other and its messy. thanks for any help

If you want the character to appear a size based on the distance across the screen.. try:
self.zoom_x = (@character.screen_y * 0.2).to_f
self.zoom_y = (@character.screen_y * 0.2).to_f

you mean .02 and it didnt work
