Help with boss spawn event

[Ellessarr]

ok, guy currently i’m working on the level boss and working on his spawn, while i did the “basic spawn” and works fine, it’s not what i really want, here my current spawn:
1- i’ve created a “spawn actor” to spawn my boss here the bp:

it’s basically works like, when the player "enter the collision cube it will wait 5s then spawn the boss then destroy the actor.

then in the ai controller i have this:

ok here the thing, i want to when i enter the collision zone, the boss will spawn without the delay but before he start to “run” the behaviour tree, he will play a montage animation which is a “entry for the boss” then after that it will have a "delay for a small entry dialogue box, then after the delay and dialogue finished he start to run the behaviou tree, don’t worry the player character is also paused during this time.

basically i want to create a “event” just after the boss spawn, where the game will do a sort of pause, the boss does his entrance a dialogue comes then after that event end the fight start, the dialogue stuff is not a issue i can handle it, the issue is to control the AI to after it spawn, it will do it animation entrance then after x time it wil start to run it behaviour tree.

how i can do that?? any good tip or advice, or tutorial, as i told i’m just want to know how to proper control the ai to do the event properly which is do it entry animation then after x second which it will really start the battle, before that the boss will play the animation once then will be "waiting until the event ends to start to really proper act.

i’ve already tried some stuffs but nothing worked, currently one of the issues is which the AI already start to “running the moment it spawn” and i can’t say it to “wait” for the event before it start to “act”.

the best i managed to do so far is just make the boss spawn after the “pause” event, which is not exactly what i really want.

what i want is like some old games like megaman:

you reach the boss point then or the “dialogue event play first” warning the boss is coming then the boss spawn and do it animation entrance then after the animation the battle start or the other way

you reach the boss point then boss spawn and play it intro animation then the dialogue comes then after x time the dialogue ends and boss fight start.

Hi @Ellessarr

not an expert about A.I. but you should be able to share some variables with a blackboard and make the A.I. react to that,

So you can spawn it, but he check the variable you make lik “cinematic pause” and so do nothing
until you , at the end of the dialogue, set the “cinematic pause” to off,
and so he may start acting properly

interesting, at first i was trying to do it outside the BT in the blueprints, like instead of calling the BT at the event beginning play, do it on a tick and put a branch condition however the issue was it didn’t worked well, maybe i can do that in the BT as you pointed

because i’m planning to use the same logic for the boss too but with some more “attacks”, then probably the same issue gonna happens then it would solve the possible same issue in a future.
