creating a custom event in the level blueprint and calling it in a class blueprint

[anonymous_user_95ba3145]

Hi, i need some help for this problem:
i’m making a simple 2D side scrolling game, i need to make the player pick up coins (like super mario, a simple overlap event).
I created a custom event in the level blueprint (which contains many of the game, score, highscore, coins, ecc), but i want it to get called by the blueprint of the coin (coins spawn randomly). I’m stuck on how could i call the custom event in the class blueprint. i tried to make a variable which contains the entire level but i get an error.

some screenshot:
this is my level blueprint

(i’m using console command as debug tool)

here’s the coin blueprint, in the red circle i need to put the custom event call

You can use eventDispatcher for this
but to better orgonize your work , you can put your variables ( score, highscore, coins …) in your gameMode and cast it every time you need to change a value

wow, thank you for both advices. I think i will move the code from levelBP to gameModeBP.

Btw, do you know any tutorial or example to suggest on the usage of event dispatcher? i never used them and i found the official documentation incomplete…

in your situation it can be a little tricky cause the coins are spawned randomly .
In general :
in your coinBP , you create an event dispatcher and call it
in your scene you select your coins and go to LBP, right click and tape the event

You Can look into my Tic Tac Toe game sample , i used it to update score

thanks a lot!

so, i firstly tried to move the code to game mode BP instead o level BP, it’s actually more clear.

this is the function i made in the game mode BP

while this is what stay in the coin BP

where swarm swarmGameMode is a variable that should contain the game mode BP

with this code the event in the game mode BP is nevel called.

so i tried with the event dispatcher:

first i created an event dispatcher in coin BP and called it

sorry for the lame question
but then, in the game mode BP, i didn’t understand how to make that event to actually make something

[Mhousse1247]

maybe your swarmGameMode instance is empty

you can try this

or this
