Hi, I have a question regarding the sequencer. I’m making a short video, for it I want to use line traces for a specific purpose, I was wondering how I could use this function I made in my blueprint, either on tick, or in the sequencer. Is it something possible or keyframable or can be enabled on tick even without beginPlay? Thanks.

Hi,  
depending on your use case, maybe EventTrigger will be enough? Just add your actor to sequencer and add it like that:

Then you can add a keyframe with an event, double click on that keyframe and it will take you to sequence\_DirectorBP.

There you will have that event with reference to that actor, so you can call it’s events or use LineTrace:

Hope that helps 🙂

Thank you for your response, Unfortunately it doesnt seem to be working, I tried a print string too, line trace isnt showing any trace either so i have no idea if its really working or not

You also need to set a keyframe to call the event.

I already tried keyframing too haha
