UE4 按键解绑换绑

UE4 按键解绑换绑
具体要用:UInputSettings::GetInputSettings()

简单测试：

TArray outMappings;
UInputSettings::GetInputSettings()->GetActionMappingByName(TEXT("Jump"), outMappings);

for (int i = 0; i < outMappings.Num(); i++)
{
UInputSettings::GetInputSettings()->RemoveActionMapping(outMappings[i]);
}

//移除一个已经添加的按键事件
//UInputSettings::GetInputSettings()->RemoveActionMapping(ActionMap);
//保存按键事件表
//UInputSettings::GetInputSettings()->SaveKeyMappings();
