i want to create a dropper that spawns and maintains 2 (reflecto)cubes
So if one drops into the water, one gets respawned, and if 2 drop in the water, 2 get respawned.
How do i go about creating such a dropper?

Things you Need:

at Least
1X Prop_dynamic
2x Reflectocubes
2x Point_template
1x Button/Trigger to open/close the dropper

First create a Prop Dynamic with the Model of an ItemDropper, in the Properties change the part Hold last animation to "yes".

Then Create two Reflectocubes as usual and give them different Names.
For Example RefCube1 and Refcube2. Put them in or above the Dropper (Whatever visually fits your needs)

Then Create To differently Named Point Templates.
For Example RefCube1_Template and RefCube2_Template and give each of them the corresponding Cube as Template.

Then add an Output to the Cube1/2 Properties.
Like
On Fizzle / RefCube1_Template force spawn
On Fizzle / RefCube2_Template force spawn

You can now ever let a button open the Item Dropper or also stuff that into the Cubes output like that
For Cube:
On Fizzle / Prop_Dynamic_Itemdroppername Set Animation Open
On Fizzle / Prop_Dynamic_Itemdroppername Set Animation Close Delay 4 seconds

For Button:
On Pressed instead on Fizzle

This should do probably what you want. If not, I'll recheck later if i'm home.
