I have been on Construct for a few months now. Really on and off, as I do not have 48 hours a day.
Today, or really, tonight, I learnt about Trigger Once. I wish I have known this earlier. Then I would not have made the very convoluted and complicated event coding I did in one of my game in progress. To its defense, yes I have read the whole manual, but flood of text is not the best for me as I am a visual learner. I went to actually read some tutorials on logic (sounds boring) and there it is!
