foxycodes I click on the button it works once not twice or more.
Sounds like you did something wrong when... connecting the signal??? How exactly did you do this? show code or screenshots?
I can only DEDUCE so much. the ways I can think of to connect a signal are from the signal panel next to the inspector, and from code. For the first we need a screenshot to diagnose a problem, for the second we need the code.
foxycodes I tried adding it to _process(delta) but that showed me an error.
adding what?
I recommend that you read the docs or follow some tutorial before jumping to code if you have no experience with godot or coding in general.
