Wait a time but without repetition and other questions

Hello. I have some questions. Thanks all. Sorry by my English.

1.How can I wait a time? I want to say, I set rate of particles from 0 to 200, then I want to wait 2000 miliseconds, and then I want to set rate to 0.

2.I have a sprite, and I want to move it to right a given distance, then I want that it returns to left and then restart.

3.This is difficult, but... You can connect with a MySQL database online?

THANKS.

If you don't understand something say me. Because my English level isn't too good.

I can only help you with the first question. Try to do this with a function object.

For example:

+ Start of layout

-> Set particle rate to 200

-> Call function "particles" after 2000 ms

+ On function "particles"

-> Set particle rate to 0

—: Take a look at the Sine behaviour. On the forum you will find a nice tutorial cap for it.

—: I would say you will have to reach for an external python library to do that I think. I do not know if you can do it with the HTTP object or something else.

I tend to agree about having a look at the Sine behavior for #2
