Wait for World_Imagery Layer Load

BenSBaker — Mon, 23 Jan 2023 16:34:31 GMT

Hello,

I'm currently attempting to create a first-person simulation of a city, where one can walk around. However, I'm having trouble with the world_imagery layer mesh colliders loading. The player is falling below the world, due to the colliders not being available immediately.

My current solution is to wait for a fixed amount of time and hope they are loaded, then spawn the player in. However, I'm hoping for a more deterministic system using an event. I've looked into the ViewStateChanged event and LoadStatusChanged event. Both reach active or loaded before there is a mesh available. Is there another component I could use or a different approach I should try?

Thank you for your time!

One method you could consider is to check colliders using raycast.

Based on your suggestion, I implemented a Coroutine that waits until the Physics Raycast returns true. The player is initially higher than the ground, and using a small max ray cast distance prevents it from being triggered from the initial load of the layer.

Thank you for the help!
