How to make swingcopter gameplay without using dual portals?

This is a way to make a floating-ball gameplay that does not use the classic double portal and the line of blue orbs. Here the steps(based in the level Mission Madisson by AgentJDN)

0) Create a simple entry with a ball portal at the end


 1) Build 2 long rows of blue gravity portals and assign two groups to the pack, (one to be activated by the toogle-touch and another to make these portals invisible). Groups 1 and 500 respectively were used.

2) Then, build 2 long rows of yellow gravity portals and assign two groups to this pack, (to toggle-touch / alpha ) . Groups 2 and 500 respectively were used. (this is similar to step 1).

3) Create a column of triggers, two of Toggle Trigger and two of touch trigger.

In a toogle trigger check "Activate Group"

In this example:
        Group 1: blue gravity            portals initially enabled        check"Activate Group"
 
        Group 2: yellow gravity         portals initially disabled        don't check "Activate Group"



4) In the touch triggers uncheck all (default setting). That action will alternate the activation of the groups of gravity portals between normal and inverted in each click, (flipping the gravity like a floating ball gameplay !)


5) Finally make all portals invisible and create some random gameplay.

-This also works with the spider (after jumping the slopes)
-This way requires more objects than the way of dual portal 
-This can be combined with freefly gameplay (requires more than 2 rows of gravity portals)

And that's all for now
