What is Immediate conditions?

What is Immediate conditions(Red color condition in Event editor)?

[Looki]

They are triggered. You can't negate them.
E.g. "User clicks within area XY" is an immediate condition, since it's triggered once - when the player clicks within the area.

What meaning is "Immediate"?

The operation result is the same regardless of the condition in the first(Red) or the second(NOT Red).

"Immediate" as in "immediately".

Normal events in MMF are checked periodically (50 times per second) to see if something should happen.
Immediate events happen completely independently of the normal events.

If you try to use fastloops, you will see that while a fastloop is running, no other events are running until the loop has finnished.
That is because fastloops are finnished immediately after you tell the loop to start, only then can the game/app continue to run.

Other immediate events are when the user presses a button or clicks the mouse. You will see that it doesn't matter where in your entire list of events you put those immediate events, the outcome will always be the same.

For example theese events:

Always: set counterA to 1
Always: set counterA to 2
Always: set counterA to 3
On clicked with right mouse: set counterB to the value of counterA

Will act just the same as:

Always: set counterA to 1
On clicked with right mouse: set counterB to the value of counterA
Always: set counterA to 2
Always: set counterA to 3

In both examples "counterB" will have the value of '3' even though it doesn't look like it in the last example. That is because MMF checks for mouse clicks at the end of each run though the event list (50 times pr second by default).
So in that sense, the immediate events was triggered immediately when MMF detected the click (in this case at the end of the event list)
