Help with Listener on SprintStartedEvent- Copy Custom Field Value to Assignee

Question

I am trying to create a Custom Listener that fires on the SprintStartedEvent.

What I want for the outcome is when a Sprint is started the value that is in the custom field "Planned Assignee" which is a single user picker field will be copied into the Assignee field.

I am not sure how to get this started. I haven't been able to find any previous questions asked that are helpful in this situation.

I'm really sorry I can't test for you but you need to try something along these lines.

import com.atlassian.greenhopper.service.rapid.view.RapidViewService
import com.atlassian.greenhopper.service.sprint.Sprint
import com.atlassian.greenhopper.web.rapid.chart.HistoricSprintDataFactory
import com.atlassian.jira.component.ComponentAccessor
import com.onresolve.scriptrunner.runner.customisers.PluginModuleCompilationCustomiser
import com.onresolve.scriptrunner.runner.customisers.WithPlugin
import com.atlassian.jira.workflow.TransitionOptions

@WithPlugin("com.pyxis.greenhopper.jira")
def historicSprintDataFactory = PluginModuleCompilationCustomiser.getGreenHopperBean(HistoricSprintDataFactory)
def rapidViewService = PluginModuleCompilationCustomiser.getGreenHopperBean(RapidViewService)

def user = ComponentAccessor.jiraAuthenticationContext.getLoggedInUser()
def sprint = event.sprint as Sprint
def sprintState = sprint.state

if (sprintState == Sprint.State.ACTIVE) {
def view = rapidViewService.getRapidView(user, sprint.rapidViewId).value
def sprintContents = historicSprintDataFactory.getSprintOriginalContents(user, view, sprint)
def sprintData = sprintContents.value
def issueService = ComponentAccessor.getIssueService()

if (sprintData) {
def issues = sprintData.contents.issuesNotCompletedInCurrentSprint

issues.each { issue ->

def issueId = issue.id

def sourceField = customFieldManager.getCustomFieldObjectByName("Planned Assignee")

// put the rest of your code here

}
}

So in the example, everything above line 21 if (sprintData) is somehow grabbing the issues from the Sprint. Okay. I still don't understand at all how I would call the custom field "Planned Assignee" and use that to populate the Assignee field because the only way I know how to do that is using script with issue in it (issue.assignee, event.issue, etc).

If the example is somehow showing that then I do not understand how.

Yes the event is a sprint event and not an issue event.  You need to get the issues out of the sprint event as per the example in the Library (although that's for the closed event the logic is basically the same). 
So this line here the value would be null.  def issue = event.issue as issue
