I am using Blueprints and know how to create a sphere trace, but curious if in Blueprints it is possible to do a Sphere Trace By Channel to start small then get larger over time?
Somewhat like a explosion would be like… it starts small then increases…
A single sphere trace only last for the frame it was spawned. So if you spawn your sphere trace with a radius of 10, it will look for a collision in that exact moment. If you want to make the sphere bigger over time, you can use the event tick and the delta seconds to increase the radius, for example, each second and also call the trace again with the new radius.
You could use a gate that opens due to certain events and let it call the trace function multiple times before it gets closed again.
Just some thoughts (: I hope this helps you. Feel free to ask me if you have some more questions to this.
