I’m new to UE and i’m trying to figure out how to set up my project.
I have some base class which few other classes derive from. Each derived class has its own mesh ,texture ,… , which I set up with blueprints. How do I use those blueprints when i want to spawn some instances of those classes ? All instances are spawned trough some controller class.
Is that even possible or i have to hard code all that stuff ?
In order to spawn those classes, you need to use the SpawnActorFromClass node, specify its class and Transform (Location, Rotation and Scale):
I’m not sure that’s it. I want to apply already made blueprints to an object which i spawn trough code ,not editor ,who’s transforms are also controlled in code.
What do you mean by “apply already made blueprints to a object”?
Let’s say I have some class named Cat and I create a blueprint for it too.
Now i want to spawn 20 of those Cat blueprints somewhere in the world trough some logic in c++.
How do i do that ?
In C++ you have to get the reference to your Blueprint class. You can either use Constructor helpers to hard-code the path to your Blueprint or use UPROPERTY (variable of type TSubclassOf) to do that. Once you get it, simply use SpawnActor() (look at the documentation for examples).
What @xSheim said!
UPROPERTY(EditDefaultsOnly)
TSubclassOf<ACat> BlueprintToSpawn;
Then spawn that class,
If you find my answer good, please mark it as the answer to the question, so others will be able to find it easier
I think i’m not getting some steps:
In my controller class ,with TSubclassOf , i can get the reference to one of derived class blueprints and then spawn it. I do that by creating a blueprint of controller class and changing ‘blueprint to spawn’.
What i don’t understand is how do I set default blueprint for each derived class. I don’t want controller class deciding which blueprint to pick. It should be on each of derived class to do so.
