Scale from 0 to 1 (Object Pooling) in UE4 

Cool video but honestly if you are not going to interp that 0-1 over time just shift from 1-0 you might as well just make use of actor hidden in game or visibility. With your step on the block for example you have a minor hitch cause you bounced off the object basically, you could easily of set that to just go hidden in game collision response = none and play that particle this way you would fall right through without the hitching. Add a small lerp time to that 0-1 so things grow in your hands or whatever and it would make more sense to use 0-1. Either way cool video I enjoyed it and subbed keep um coming I love watching how other people do stuff.

like Ryan said before me i'd be interested how this compares to hiding and disabling or changing collision of actors. thanks for the quick and informative video though!

And thank you, this is that top shelf content the world needs!

so say if you have a program where a character has say 30-50 weapons and items to equip and choose, does that mean youd want them all equipped at the same time on the player to switch between different options? Or would you be able to put a parent blueprint of the items that could swap out between all of the options available to save resources?

I ran into a similar obstacles with doing my game Tesseract Prime Offworlds but i like the idea of shrinking down the mesh instead of deleting it and then having to respawn it in again, is this instancing and removing is what causing the slow memory leaking in Unreal Engine?.. . Because Unreal Engine does have an issue with slow memory leaking when you leave the engine running on by itself for a period of time, things tend to slow down by themselves in it after a while and that's by not doing anything at all in the engine and just leaving it in idle mode for for a few hours or a day or so. So I'm not sure why the engine slows down after a while when you leave it in idle mode.....And the refresh rates begin to slowly change the longer you leave it running...I think there's an issue here with the pie editor. FINDING THE MESHES: The biggest challenge I have is finding all the resources for all the different characters on the different worlds and the one thing I notice is a lack of buildings that are all hollow, for most of the building meshes seem to be just solid meshes that you walk all around, but in my game I need to be able to go inside some of buildings interiors as well, not just walk only around just the exteriors. If I use a building modular system, then I could bog down the engine with too many meshes pieces just to build the city or buildings..... And also Mixamo Animations have got a problem with targeting other skeletons in Unreal Engine. It dosen't like Unreal Engine. PROCEDURAL SPLINES I'm reluctant to resort to Splines to try to procedural generate the buildings in the world because splines are known to mess with the construction script. GODOT COULDN'T EVEN CHANGE MY SKELETONS. I was thinking of putting my game inside of this engine but I could not change the skeleton of the demo mesh that was in it I couldn't replace their mesh with my commander's skeleton. They don't have change mesh option yet as Unreal Engine has.. So to change the mesh I think you would have to redo the code that mesh is using. DIALOG SYSTEM WORKS BUT I've been using Validated Get to turn the widgets on and off in the game with remove from parent. Which seems to work. I got the basic dialog up and running in Unreal Engine with the help of others in the community But I have to find a way to track the different planets and systems also in the game (keep track of the different worlds that you visit) You also need an Ai Master Controller System to control all the other AI Controllers that are in the map so that we don't have them all running all at once. Layley is busy doing a video on that to show us how to manage all the AI in the map.. DIALOG CHOICES WIDGET WHERE DO WE START ON SETTING THIS UP? Not sure how to handle dialog branching choice menu up to go with the dialog text system. GLOBAL MANAGER NEEDED FOR STORYLINE PROGRESSIONS AND QUESTS TRACKINGS ON EACH WORLD. I need to know how I can store all dialog storyline progressions flags that change dialog branching to trigger off certain events in or events in the game. I have already written out all the dialog branching of storylines in notepad for most of the different worlds. Like Kotor did with choices and consequences flags in the menu dialogs. Except they used a dialog tlk node editor to construct their dialog and turn on or off certain flags with the dialog editor to trigger certain storyline events in the game while I just used simple Notepad and a whole bunch of Array nestings in batch code to try to construct all my dialog branches which also worked.... That way I saved myself thousands of hours of constantly firing up the engine all the time just to edit changes to dialog when i can make all the changes outside of the engine and then just cut and paste the dialog into the data table, er yeah. .. So far I have been stringing storyline events as booleans switches and storing them up in the Game Mode BP. Gets Complex when it involves activating storyline and quests flags on different worlds... And that includes also dealing with Different Councils Issues you run into also on those different worlds and Diplomacy and Trade issues among the different Factions and Conflicts on different worlds with Council Treaties also Vendors who either sell you good or bad stuff. A global manager also for tracking the different planets you've been to or systems you unlock. Keep track also of the items you pick up in each planet. So my game is a little complex.. So I'm not sure how you keep track of everything going on all the different worlds yet. Does anyone know how to make a global management system for all this stuff I need to keep track of? When it comes to dialog storyline progression. I know how to do the storyline progressions with just one world but with tracking of many different worlds storyline events? That I only how to do that in batch code, not in unreal engine yet... The game also has a level progression system, inventory system. but I don't know if the inventory system or its level progression system is set up for global progression across all maps yet or just only works for the currently loaded level in the engine.. I guess i have to load in another level to find that out. So I just chucked the item flags changes and storyline triggers into the Game Mode BP for now. But I might have the wrong BP to store the global flags in. I think Game Mode just stores up in memory what's in the currently loaded level... If that's the case then it will only track whats in the currently loaded level in memory. Still what is stored has to be saved into a save file. So it is only game mode for storing one level and the game instance for storing all the flags for all the other levels? I'm not sure how you set up these type of choice and consequence games in Unreal Engine. The game is not being built with World Composition, as I don't know how Unreal will handle switching between worlds to different party members if you give them missions to do on different worlds. Currently they do only do on one world at a time that the party visits. Either that or my game is a little too complex for the engine. But Kotor was able to do a complex game with alot of dialog, so it should be possible. The dialog part is not a probem, but all the flag branching progresssions of different events in the dialog is. Unreal engine should be fast enough to just switch instantly to different worlds but I think at the moment that Playstation 5 can only do that.. Unless you have to use world composition. I thought I would explain what some my challenges are with trying to set up my game in unreall engine in case someone has some solutions to these limits that I ran into. Including also the memory leak issue as well.

As a newbie who has just recently started learning UE4, this is very useful! It makes me curious though, just how many similar tricks do game developers utilize?

can this be done thru blueprint? bcoz i hope you can make a tutorial for it. Although this is a good video, but i dunno how to create it lol
