Hi guys

I often read the posts, but i'm unable to find some doc on how compare gem objects coodonates.
It is for a little game project; shooting aliens projected on a surface with balls you throw on it. I need to know how compare aliens coordonate with balls coordonates.

Thx

Nico

Hi,

I work on PD since a few month. I need to use gridflow but #object can't be create, does someone know how to make them work ?

But perhaps it must have an alternative; I need to locate a man position with a camera.
I want do divide my screen in 9 zone (like a grid). Each zone is waiting for someone coming and when the man is locate on a zone, it trigger a video.

I don't know where to start.

I was thinking that i can make the virtual grid with picking coordonates of my screen;
for example : -4 -3 for X & 4 for Y is my first zone.( in open GL)

Don't hesitate to ask me more infos if you don't understand my need.

Thanks a lot

Nico

Thanks for your quick answer.
I use [translateXYZ] but i don't know how to make something that compare the data.
I need to bang when the ball coordonate and the video coordonate are similar.

Hi, i have a problem with grid flow : #objects don't work.

How can i make them work ?

HI GUYS. very nice stuff. I work on a reactable too and i see i am not alone.
I know how to display the true wave form ( with scopeXYZ ) but i have a problem with rotation, it doesn't work in the good way. but the display of the wave form is ok.

hi, i am working on a reactable project and i need to learn more about cartopol object. i would to convert the cartesian coordonates of a symbol captured with the camera to polar coordonates in OPEN GL.
I open cartopol but doesn't understand how to use it in PD.
Thanks for your help.
