Within unreal engine 5.2 blueprints, I set a “PC_left_door” with physics constraint fixed, so left door does not rotate initially.
Then I roll a ball on ground (ball_2). When ball_2 overlaps collision box, I a set angular swing limits to free and print to screen. If ball_2 overlaps collision box1 in less than 2, all works correctly. Door rotates, and string is printed to screen. If ball_2 overlaps collision box1 greater than 2 seconds, door does not rotate, but string is printed on screen. I have tried many variations of this with the exact same result. How can I get the door to rotate after 2 seconds?
I am a beginner at unreal engine, making first game. And this is my first question I have asked on this forum.
Can you post a video?
as new member I am only allow to add one image. I showed my blueprint and a picture of the scene with the door in the up position fixed. When the silver ball moves to the right, it goes through the collision volume. As stated, if less the 2 seconds then constraint is changed to free and the door rotates down under gravity. If ball takes longer than 2 seconds before overlapping collision volume, then the door will stay in the up position and not rotate down but the string “Hello” is printed on screen.
I found an unorthodox way to make this work. I added set enable gravity with target linked to door and enable gravity not checked. Then I added a 2nd enable gravity with target linked to door and this time enable gravity checked. Then after these two gravity nodes, I was able to change physical constraint swing limits to free at much greater time lapse than 2 seconds.
