First of all thanks a lot! You've been so much of help. I've moved in the game and am currently working with a team of graphic designers as well. The idea has changed since then, and I'm making a kind of 'arcade' game to promote music merchandise (this will be utterly free and will only be played as a concept game at this stage).
Thanks Somebody for the tips on the tick and dt, I'm still using those. The only problem I have is the following:
So, I have a scene were a moon appears after say 30 seconds. After the moon appears a variable moonAppears is set to 1 and so, the clouds come out to cover it. I've used set angle towards moon.X, moon.Y and it works perfectly. The only problem is that once the moon is displayed and motionless, all of the clouds that come out, stop and freeze into a sort of moving motion to the same position. Like being stuck to the moon and moving randomly 1 pixel, kinda shuttering.
I've tried checking the distance between the moon and the clouds in a new instance and setting the position randomly around the moon, but didn't work. Could it be because I have another instance calling the clouds and setting the angle to the moon?
Thanks for the help, I'm much obliged.
