Title: On drag & vertices increment problem
Post by: joreldraw on October 25, 2012, 02:25:36 AM

Hi, i have my Draggable panel with grid with 225 checkbox(checkmark + label)

All work fine except when i drag the panel. Ondraggin the vertices count increase about x9.

Why this? How can i reduce this? because i recieve an Too many vertices error.

Thanks

Because when you drag, the panel doesn't do clipping as clipping checks would result in the draw buffer being rebuilt every update, which is expensive. Not doing clipping makes it much faster.

Uiviewport is better solution for this? or Dragcamera?
This only render in buffer visible elements , right?

I test this, whith drag cam, and using viewport with drag panel but not is a solution.

All way enable all object on drag and the vertices count go x9.

:(

Why do you care that vertex count goes up?

Because when the element list in about 100, i can drag nice.
But when this list go to 200 and i try to drag i recieve the error "Too much vertices" and dissapear, later appear at beggining position (Can't drag )

Get rid of shadow or outline effect. Shadow doubles the vertex count. Outline multiplies it by 5.

I know, my hierachy is superoptimized, without any fx, only 1 label & 1 slicesprite pero object.

I  check that when i drag all collider go On and there is when the vertices count go Up.
Is possible to make something to paginate the grid list or be loading secuencially from the panel position?

Thanks

You will need to write custom logic for that.
