Thanks for response,Hello sercan,
So, if I'm understanding you correctly, you have a character who jumps when you touch the screen. But, when you tap, sometimes the character does not jump. It happens mostly when you are moving from one room to another.
Are you attempting to jump during the room transition? Or are you jumping right before the room transition. Although your character is persistent, I'm not sure if all of the properties of your character are persistent (movement, etc.).
I ve just figured out the problem is not only with character. I made a counter counts the mouse click ( or tap screen) also. and i put it somewhere on screen. I determined that when charater does not jump, the counter does not count also. So it is a skipped screen tap problem. what may cause this??To test whether what @Comedy Rotten is saying, create some globals, and in the Room End event copy the values into the globals.
On the Room start event in the new room, copy the globals back - or just use the globals all the time.
