Hello, I have a Little Problem with my Scenario, I made a Little Jump 'n' run game, but the actor randomly gets stuck in the ground a bit, so if I want to jump, I Need to press the key many times, until the actor gets above the ground. Here is the Code of the actor: Hallo, ich habe ein kleines Problem mit meinem Szenario, es ist ein kleines Jump 'n' Run Spiel und das Problem ist, dass die Spielfigur manchmal im Boden feststeckt, z.B. wenn ich springe, muss ich die Sprungtaste sehr oft drücken, bis der Charakter aus dem Boden rauskommt.
