Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

How do I setup a Save and Load system using Blueprint?

How do I make it so when I press a key like F1 it saves my game and then when I press a key like F2 it loads my game.

In your playercontroller's eventgraph, right-click and search the relevant key's input event. Check that F1 and F2 are not being used in the game's defaults for other purposes => I think F1 toggles wireframe display. To change that you'd have to dig a little deeper into keyboard defaults. F1 is usually anyway set to expose Settings or Info menus. F5 and F6 are often set as quick save and quick load. To really do it properly, look up Action Mapping. This is a key binding by action name, and allows the player to change keys if they want to (if you set up a menu for that), so all you have to do is map a 'QuickSave' Action Mapping to a default key.

For information on saving, search the Answer Hub, there are already illustrated examples, like here: https://answers.unrealengine.com/questions/25747/how-can-i-savegame.html

Thank you for your help! I really appreciate it. I spent like an hour trying to work it out yesterday but didn't get far. Thanks again!

I wrote up an approach to using inputs in an Actor to trigger custom Events on the separate MySaveGame blueprint: http://jevon.org/wiki/Saving_and_Loading_UE4_Data_with_Blueprints

For example, triggering "Save The Game!" event within a "SaveGameBlueprint" external blueprint from a "FirstPersonCharacter" blueprint:
