Delay between spawning new actors

[KatharinaSchmidt]

Hey, I want to synthesize datatests with objects lying randomly on the floor. The object shall also lie on top of each other, so i want them to appear at a random position in my TriggerVolume and fall down. When all object lie on the floor, the captured data shall be saved.

For now, I am using a GroupActorManager for my objects (works well, diffrent objects appear in the defined volume in diffrent rotations) and a SceneCapturer_Simple with a SceneManager_BP to save the data. My problem: a new group of actors spawn in a very short time frame, so the objects can't fall on the floor

I already tried to vary the Spawn Duration, but that doesn't help.

Can you please tell me what I'm doing wrong? Do I need another actor or component?

Thanks in advance :)

Based off your description of the problem, Spawn Duration should be the correct parameter.

Do you have any images you can share?

Here is a screenshot of the GroupActorManager:

and a screenshot of the SceneCapturer_Simple:

Please let me know, which other images are helpful for a solution.

Even if I set Spawn Duration to 0, a new group of actors spawns every frame. But the discription says: "If Spawn Duration <= 0 then we only spawn the actors once"

I appreciate every approach solving this problem.

A couple things come to mind.

Eric is correct in that the spawn duration controls the time between respawning. I can verify that this works though I do not know if I have ever set it to zero. We use group actors on every level, with varying spawn durations and I haven't seen this problem.

Here's some other things to check:

• What are the physics properties of your actors?
• is physics enabled ?
• is gravity enabled ?
• does the actor have a random movement component? If so, is the teleport option enabled? What is the speed, range of movement and time between movement settings. Is movement relative to object origin.
• have any of the project or world setting for the gravity constant been modified ?
• is your group actor positioned inside or outside your trigger volume?
• does your actor have a random visibility component? If so what is the duration setting?
• what version the plugin are you using? Prior to the commit for issue #16, the delay between capture only affected the first frame. If you have the new version you will see a delay of a hard coded 5 seconds before any frames are collected.
• does the scene appear to freeze periodically which may cause dropped frames? This is caused by many factors in the scene and/or the amount of randomization, complexity per actor.

Thanks for the help, mrkcass. First I created new blueprints for my actors, there I enabled physics and gravity. Since i placed the group actor inside my trigger volume it works.
