Combine Checks

Every Frame

Combine Checks Logic

First true | Mode 'and' | Second true

Joins two tests into one, demanding both or accepting either. It is what a condition with two parts needs before reaching Do If or Pick Value.

Input	Type	Default	Description
First	bool	true	The first test.
Mode	String	'and'	Whether both tests have to pass, or just one of them.
Second	bool	true	The second test.

Output	Type	Description
Result	bool	The answer of the two tests together.

Compare

Every Frame

Compare Logic

A 0 | Operator '==' | B 0 | → True | → False

Answers how two values compare, using the operator picked in the middle. It can branch on the answer or hand it to a field that takes a yes or no.

Input	Type	Default	Description
A	Variant	0	The left value in the comparison.
Operator	String	'=='	How to compare the two values.
B	Variant	0	The right value in the comparison.

Output	Type	Description
Yes	bool	Where to store the answer of the comparison.

Branch	Goes to
True	Where to go when the comparison is true.
False	Where to go when the comparison is false.

Is Empty

Every Frame

Is Empty Logic

not set | → Empty | → Has Something

Checks whether a value holds nothing and branches on the answer. Text, lists and dictionaries are empty when they have no items, a value that is missing counts as empty, and a number always counts as something.

Input	Type	Default	Description
Value	Variant	-	The text, list or dictionary to check.

Branch	Goes to
Empty	Where to go when the value has nothing in it.
Has Something	Where to go when it holds something.

Is Near

Every Frame

Is Near Logic

A not set | B not set | Distance 4.0 | → Yes | → No

Checks whether two positions are close enough to count as the same spot. Use it to tell that something arrived, since a value that eases toward a target keeps getting closer without ever landing on it.

Input	Type	Default	Description
A	Variant	-	The first position, such as where the node is right now.
B	Variant	-	The second position, such as where it is heading.
Distance	float	4.0	How close the two have to be to count as arrived, in pixels or units.

Branch	Goes to
Yes	Where to go once the two are close enough.
No	Where to go while they are still apart.

Is Valid

Every Frame

Is Valid Logic

not set | → True | → False

Answers whether an object is still alive, which is false once it was freed. It can branch on the answer or hand it to a field that takes a yes or no.

Input	Type	Default	Description
Object	Variant	-	The variable holding the object to check.

Output	Type	Description
Yes	bool	Where to store whether the object is still alive.

Branch	Goes to
True	Where to go when the object is still valid.
False	Where to go when the object has been freed.

Pick Value

Every Frame

Pick Value Logic

Condition true | If True 0 | If False 0

Picks between two values depending on a condition and keeps the chosen one.

Input	Type	Default	Description
Condition	bool	true	The test that decides which value is taken.
If True	Variant	0	The value taken when the condition is true.
If False	Variant	0	The value taken when the condition is false.

Output	Type	Description
Result	Variant	The value that was picked.
