Thanks a lot. I finally find it,very important the input mouse property to yes.Why not set this property by default to yes,since touchsmartphones are common today? 2)There's any game,pictures or video that shows a real game made with construct 2 where the player shows is touching the screem of an iphone or table while handling the 4 arrow keys. Is it required to create a 4 sprite arrow keys objects in order to play on a touch smartphone. I have seem other games where these 4 sprites arrow keys are not there. The player just touch the screem and that's it movement come.3)I also have seem here in some posts that is recommended to just use one sound or track for a game.Either you use the background track for the game without the sounds for the game itself or you just use the sound for the game like when you jump,shoot,or get new achievement in a game without the background sound. It's better a game with the two sounds:the background music for the entire level,and the sounds for jumps,killstreaks,new achievement.so, regarding sounds what is the best to do for a well constructed commercial game made with construct 2? Thanks
