How to make a piano lid lift slowly

[palistov]

Try this:

PHP Code: (Select All)

int pianoTick=0;
float fPianoStep=0.02f;
void PianoLift(string &in timer)
{
    pianoTick++;
    if(pianoTick > 50) return;
    SetLeverStuckState("pianonamehere", fPianoStep*pianoTick, false);
    AddTimer("", 0.05f, "PianoLift");
} 


This loop repeats very quickly to constantly be adding a small upwards force to the lid. You'll definitely have to tweak values to get it right since I have no idea what force values you'll need. Initiate it by using a timer with a duration of 0.01f, so it basically triggers instantly. Also, replace pianonamehere with your piano's name. Don't change the _BodyLid suffix, that designates the entity body to apply the force to.

LATER EDIT: Well I was curious so I tried it out in-game. Doesn't work very well, even with a custom entity with modified properties. The reason being that the object has gravity so it just falls back down. It works for doors though. :3

I'll try more stuff later, I have a few ideas in mind. Ropes and stuff.
