Are you using a Unity version from 2005? /s

alaa2008OP•2y ago

i am using the version 2017.3

Buddy•2y ago

Why? Just install Unity 2021 and you should be good

JakenVeina•2y ago

I mean, theberrorbis pretty clear: you're using a language feature that's not supported in C#6

alaa2008OP•2y ago

the project was made with this version

JakenVeina•2y ago

either don't use that, or changenyour C# version

alaa2008OP•2y ago

how i am new to c# sorry. so how am i able to fix that ?

JakenVeina•2y ago

what line is the error?

alaa2008OP•2y ago

JakenVeina•2y ago

yeah

alaa2008OP•2y ago

its the out thing

JakenVeina•2y ago

change that line to be valid syntax for C#6, or lookup how to change C# versioning under Unity

alaa2008OP•2y ago

ok thx bro this one here ?

alaa2008OP•2y ago

ThatDaniel•2y ago

just replace the var with the type thats your issue. C#7 implemented using var with out you cannot change the C# version without upgrading the editor version

Buddy•2y ago

You can also convert a project to a newer Unity version

alaa2008OP•2y ago

how to replace it with type sorry for asking

ThatDaniel•2y ago

what is states dictionary(?) of what

alaa2008OP•2y ago

ThatDaniel•2y ago

ok then the type is State<T, K> try putting that instead of the var

alaa2008OP•2y ago

ok like this?

alaa2008OP•2y ago

ThatDaniel•2y ago

whats the error saying?

alaa2008OP•2y ago

well i gotta translate it because its german

alaa2008OP•2y ago

ThatDaniel•2y ago

oh it might be this:

State<T, K> value2;
if(states.TryGetValue(value, out value2))

State<T, K> value2;
if(states.TryGetValue(value, out value2))

alaa2008OP•2y ago

ok let me try YES IT WORKED THANK YOU SO MUCH BRO also i hope its okay if you also help me with this

ThatDaniel•2y ago

you havent got two TimeSource classes in different namespaces? I can only think that the TimeSource in the TimeManager is using a different type and not the SBS.Core.TimeSource

alaa2008OP•2y ago

Let me see If i have two thats the only namespace there

alaa2008OP•2y ago

any idea how to fix the error? this error here i mean

ThatDaniel•2y ago

does the error show in the Unity console?

alaa2008OP•2y ago

no only in visual studio

ThatDaniel•2y ago

restart visual studio

alaa2008OP•2y ago

ok nope i am still getting the error but the error doesn't appear in unity

ThatDaniel•2y ago

If you can enter play mode then I've got no idea why VS is saying its wrong

alaa2008OP•2y ago

let me try now i am getting the error in unity

alaa2008OP•2y ago

ThatDaniel•2y ago

Honestly cannot see whats wrong with that try restarting Unity

alaa2008OP•2y ago

yea i know why the error appears i have another script called FSM and there is another error with the timeSource this one here

alaa2008OP•2y ago

alaa2008OP•2y ago

this one here is the in the timeSource script and this one here is in the FSM script
