Sorry but if every object had the same z there would be no depth. Objects must be at different z heights in order to see a difference, hence the reason why zero is on the ground, and 100 is kicking in your teeth. Besides you can use families to change multiple object's z at one time.
If every object had the same Z? Oo What on earth are you talking about heh. I just want to have a function that adjusts exactly where the camera is located on the Z axis. if objects are greater than 100 beyond the camera, then they are culled out. Using families to adjust it requires all objects to have the same variables which pretty much destroys the concept of "Making a project with more than one type of thing" that relies on z-depth.
I'm just trying to get as 3D as possible with Construct
