Introduction to Maya - Modeling Fundamentals Vol 1

This course will look at the fundamentals of modeling in Maya with an emphasis on creating good topology. We'll look at what makes a good model in Maya and why objects are modeled in the way they are.

hey

i want to emit a particle every time an object rotates 90 in the Z axis.

float $Value = "getAttr frontGunGroup.rz";//gets the .rz
//value and assigns it to a variable

if(($Value % 90) == 0)
setAttr bulletEmitter.rate = 25;
//% is modular(?sp) so i am asking it if $Value divides by
//90 and has a remainder of zero it sets value of 25

i dont know if im barking up the wrong tree as i cant get it to work.
i think i need an else command in there as well

I'm not really familiar with MEL but didn't you say 'every time'?
I think you need to reset it later, otherwise bulletEmitter.rate will be equal 25 from the first 90 degrees and forth.

When in doubt, delete history and freeze transformations.

yes ur right i need an else statement

i used this
bulletEmitter.rate = (frontGunGroup.rotateZ % 90) ? 0 : 25;
//code to make emit on 90 degree intervals

however it emits with a rotate value of 0
i need to omit this value any ideas how
