Example 39 with Cause

use of org.spongepowered.api.event.Cause in project SpongeCommon by SpongePowered.

the class CommandSourceStackMixin method impl$updateCauseOnWithWorld.

/*
     * A note on why we're doing this with the cause manually.
     *
     * When the object is first constructed, we get the cause from the stack manager. However, as the command processor
     * works through the nodes, this entire source may get replaced. We want to keep some of the changes in sync,
     * but the original cause may have gone by the time the source changes. Really, this command source is the analogue
     * of our Cause, NOT our CauseStackManager, so we just need to do `Cause.with(...)` along with their select `with*(...)`
     * methods.
