Thank you very much for your replies, mystazsea and —
The big problem is: I'm not creating an original game - but porting an old one (so I can't change the position of the platforms).
Years ago I've released my first game ("Tcheco"). It was made in Construct Classic and can be seen here:
And "Tcheco" is an jump-thru extravaganza. They're everywhere.
In this stage, for instance, there are 8 jump-thrus in the ladder + a few others in the background:
I wanted to update my game (since I'm not 100% satisfied with it) and tought that would be a good idea to recreate it in Construct 2 (instead of fixing the old Construct Classic version). After all a C2 game could be exported to other systems and I could create achievements for Steam version.
But after some weeks using C2 (20 of 65 stages are done) I honestly don't know what to do about this update.
It plays like a prototype of CC's version - not an evolution of it.
The main character keeps "teleporting" to higher/wrong places all the time. You can also avoid falling from platforms (if you go back fast enough after falling starts). I've sent current version to a friend without telling anything about the jump-thru problem -- but he noticed and mentioned it immediately after testing.
I'll accept Aphrodite's suggestion and try to make my own jump-thru system (but I honestly doubt that I'll be able to create it). If it doesn't work I guess I'll have to abandon this C2 remake and go back to Construct Classic.
Thanks again for the replies. Any new comments are welcome!
