It depends on how similar they are and how famous the other work is.
In your example, you said you named your characters 'constructs.' The word "construct" is a common word, so it might be alright to use it as a descriptive word. However, if another author who is more famous than you has a group of creatures who seem almost identical to yours and are called the same thing, then you might have accidently picked up the idea from that author and you should pick a different name and change them a bit. Otherwise, the original author could sue you for copying him.
You might check a thesaurus and find other terms that mean the same thing, or even invent a word yourself and say it's these characters' name for themselves.
they are similar because they both change into something
Change is already a verb. For example "to change something" is an action and therefore a verb. Another verb is exchange. As in "to exchange something for something else".
a physical change , something that is one thing but change into another
to change something = sheenah (×©×™× ×”) to swap something for another thing = hekhleef (החליף)
To change something to another use or purpose
morph
To switch something, the answer would be Change
the change from someone or something to another
A character arc or change from one personality or attitude to another is typically representative of a dynamic character. Dynamic characters undergo significant internal development or change throughout a story, as opposed to static characters who remain unchanged.
Yes. There are costumes that can be found throughout the game. Or you can hack it or something like that.
You have to edit the savegame using action replay, or something similar.
Not true, they are not similar; a chemical change is a change in the molecule, the physical change is not.
