Title: [SOLVED] Problem with Global Variables trying to Set Dialogue Image
Post by: JoeGameDev on October 19, 2022, 09:23:31 PM

Hi everybody!

I'm trying to create a dialogue system that has an avatar in the dialogue box to indicate who's talking. I watched the tutorial by Bliz Studio on YT and followed it, I believe, to the letter. However, I've encountered a problem. Screenshots are included.

The first screen shows that my Dialogue Manager FSM creates a Global Variable called Dialogue Avatar. I am supposed to be able to use that variable in any other gameobject to change the image shown. Per my second screenshot, when I click on "Specify Game Object" I cannot specify that Global Variable as he does in the tutorial video. It only gives me the option to create a new one -- which doesn't help me at all. Also odd, when I click the = button besides the sprite window, I am given teh option to use the variable I want THERE, but again this isn't useful. In the tutorial, he specifies the game object as the global variable and then selects the desired sprite, which then populates in his dialogue box.

Any suggestions?

Thanks! That’s got to be it, I just need to figure out how to make sure it’s right.

GOT IT! Okay, so my issue was as DJ said: I was using two different global variable types that weren't compatible with the other actions. So rather than using UI Image Set Sprite in the dialogue manager and then Set Sprite in the FSM to control the image, I used UI Image Set Sprite in both, and VOILA! Works like a charm.

Thanks for your help, Jay!
