Thanks — for your advice!
I didn't see a loading bar using F4, and the problem solved somehow... when I restarted Construct 3.
Everything loaded smooth and fast with the sounds. I'm not sure what cause this I hope it won't happen again so I won't need to restart Construct 3 everytime while working on the game, I will have to see if this happens again or not, but from your explanation I understood that the sounds already pre-loaded so it can't be the reason, it's not loading it as I start playing.
You did encourage me to explore how to make my own Progress Bar / Loading Layout as the very first screen of my game. I will check it out hope it's not too complicated to create.
For now I have only 1 layout for the game itself, and many other layouts for sake of organization some of them have only the Enemies, Other have Items, so every one have it's own dedicated Event Sheet and all events included in the actual "GAME Stage" Layout, loaded at the top.
It's a bit off-topic but I hope that I'm thinking correct about the order of my layouts:
1 - Loading Layout = Custom progress bar & graphics, if I'll find out how to do that of course)
2 - Main Title Screen Layout = Press START to play / Options / Credits etc..
3 - First Stage Layout = Probably All X Stages in the same HUGE Layout, Camera will change direction to the other Stage.
4 - Extra Layouts = Option Menu / Settings for different controls such as Sounds / Music / Full Screen etc.. I didn't explore this part yet.
The thing is:
I'm not sure if I'll even SEE the Loading Layout screen... since I only have 1 stage now, it will probably faster and skip it right away.
Is there a way to cheat and SEE the Loading Layout Screen when running the game? some kind of secret debug-cheat? maybe... using "wait" ?
What do you think, also if you have any tips related to this I'll appreciate it.
