[Open Beta] Procedural On-the-Fly Animation in UE4: iTween!

[SwiftIllusion]

Yes sir, UE evaluates every instruction sent on tick and never skips one unless you specifically ask it to. Every single tween that sends an interface message will be heard as long as its target is valid and implements the iTInterface. This is why naming your tweens is very important - it allows you to listen for multiple interface messages at once and properly sort them.

You shouldn’t experience any problems with this, but in case you do there is a fallback. Every value is public and visible (along with read AND write, so be careful) through the event operator, so if you need to you can store your iTween’s Return Value then get it on Tick or some other update interval and get from it “Float Current” or whatever other value you want.

I want to note that in the next release OnTweenTick and OnTweenDataTick will be deprecated and be condensed down into OnTweenUpdate which will have everything in one package. Float/Vector/LinearColor etc. values will be stored in a struct passed into OnTweenUpdate from now on. You can continue using the deprecated ones for a few more versions, but be sure to update to the newest interface message at your earliest convenience.

As for when the next version is coming, the answer is still soon. has been instrumental in the Slate side of iTween, but I want to make sure it’s fully working (though I have full confidence in his abilities as a programmer) so I have to learn Slate first. On top of that we have a few projects going on so my free time has been limited, but I am working on iTween and learning Slate in bursts every few days. Thanks everyone for being patient

Awesome, really appreciate the quick response, that all sounds great :)!

Yeah cool, I found that fallback, biggest issue with it though is that when its tick ends the ‘current’ value becomes 0, making it a mess to try and ignore the incoming value if its 0 which doesn’t work if the tween you want is actually 0 at any point or if it goes past it, but knowing the OnTweenTick works as expected is awesome and means there shouldn’t be any issues with that :).

Ahhh no worries, that sounds better anyway indeed and shouldn’t take too much time to swap to.

That sounds super exciting :D!, keep up the great work both of you can’t wait for the new version ^^!! And goodluck with all your other projects too :)!
