Dotween: DoTween Animation script error [UNITY 2018]

[RealCosmik]

I am on unity 2018.3.5f1 I just upgraded from standard dotween to pro dotween. Whenever i add a dotween animation script to a gameobject or a dotween path script i get these errors in playmode and in editor mode.

Hi,

I just installed 2018.3.5 (I was on 2018.3.4) but I can't seem to reproduce this issue. Did you run DOTween's Setup after importing? And if so, can you copy-paste me the very first 2 error/warning logs you received so I can check them out?

[RealCosmik]

thats the first error

NullReferenceException: Object reference not set to an instance of an object

thats the first warning

second error

the editor will continuously log those errors and that warning

Something very weird is happening there (in the first error, which is causing all the others). It seems as if Unity finds the GUIStyle I pass to it to be NULL, but I verified that I initialize it just a few rows above (and indeed it's not NULL here). It's also a custom GUI initialization system that I use everywhere since ages so I'm very puzzled of how it could fail in your case (I just tried both updating my DOTween test project to 2018.3.5 and to just create a new one and importing DOTween Pro, but everything works as usual here).

Could you post me a picture of your Project folder, with the Demigiant folder expanded? Maybe something's missing there? Also, can you tell me on what operating system are you?

[RealCosmik]

my OS is windows 10

[RealCosmik]

perhaps ill try a fresh install? i'll delete the demigiant folder and re-import from asset store

[Demigiant]

Ah! Wait, I see what's happening there (though the error log seems related but not really precise if that's the case). You're missing the "DemiLib/Core/Editor/Imgs" folder, which contains Images used by DOTween's Inspector. Maybe it got deselected when you imported DOTween Pro?

[Demigiant]

P.S. In case you deselected it on purpose because you were worried of all those images being added to your build, don't worry. They're very small, and they're not added to the build.

[RealCosmik]

ahhhhhhhhh Okay yes that in fact did fix the errors thank you so much

[Demigiant]

Glad it's fixed :)
