problem Changing Scales in Script -C#

Question

Hey , does anybody know if its possible to change Scale through Script in C# ?

I tried by doing

if(Input.GetKey(KeyCode.C)){

transform.LocalScale = new Vector3 (0,-1,0);

}

when it runs this , the Gameobject Gets removed from the scene .

am i doing something wrong here ? or maybe its not possible ?

Thx.

Take a look at your `new Vector3 (0,-1,0);`

When you press C your object goes from (1, 1, 1) (I'm guessing)

to (0, -1, 0).. Making the X and Z invisible.

try writing `transform.LocalScale = new Vector3 (1,-1,1);` to see if that works :)

You can't have a 0 scale on more than one axis, since that makes it a 1-dimensional object and therefore not visible.

Ahhh , reading this again ...... was a pretty dumb question actually

i should probably just let it play an animation instead of messing with scales

Scale refers to the size of the gameobject. Your script won't work however because you have x=0, z=0 and here's the killer y= -1. You can't have a negative value in scale, that means not only does your gameobject not exist, but it actually has negative volume.

try changing the values to positive floats.

oh yeah, and you'll want to set a condition to that most likely. Your script, if left alone, will multiply your gameobject by your scale every time you press the C button.

you might also consider using GetKeyDown instead of GetKey. The faster your cp is, and the more frames it updates per second, you could see a cube going from 1 cubic unit to 100+ cubic units in one button press.

If you want the scale to decrease, enter decimals instead (ie 0.2f)

In fact, you can definitely have a negative value in scale. It's quite useful for flipping objects on an axis.

I've never tried, in any case having 0 for x and y would give an invisible object regardless of the scale on z.
