set specific speed to an object | Forums

[Inner.Peace.]

If so then personally I would do something like set it to be flying using the OPE, then split a trigger to turn off the OPE and at the same tick to activate a 'Force' (I forget the name of it, it is the arrow) which should be glued to the front center of the plane pointing directly infront.

And there we have the problem =D If I am right when you deactivate the OPE the plain will have the speed cero because you just changed the position of the object not its speed. so if you turn of the OPE it will have no speed at all, but you want it to continue flying. when you aply a force to go imidiatly to the speed you want you will have to set the force to an infinate power otherwhise the plain will stop and than regain speed. With a normal force there is no possibility to imidiatly get an object to a specific speed.

I found a better example: you want to shoot a canon ball at something and dont want it to slowly build up its speed but just start with a specific speed.

Well using any force as you say yourself you can't ever get it starting at a specific speed. So perhaps lets stick with an OPE the whole way through? What we have talked about with the ball will do just that, instantly start it at that velocity.

With the plane you could tie in the Y value to a variable data source and at the point you want it to crash have that data source starting at the 'cruising height' then slowly lowering > lowering fast. Could also add object rotation in that way. Both examples I would say are achievable and easiest through OPE

Seems to be the only way. the cannon ball will be not able to hit something if you use the OPE.
Im not happy with that and will devenitely write a "set object speed event" on the wishlist in the forum.

Technically no, but you could create the illusion it had using other means

Hey Chilli, I just saw that there are 'Emitters' where you can pick what object to emit and choose its start velocity and direction. Pretty much an easy solution

Wow nice solution for the cannonball and even the airplane really nice solution mate!
That fixes the absence of an "set speed event" for the cases I can think of till now,
but a "set speed event" would make this much easier!
Again nice fought.

I wonder if you could make a copy of the plane, OPE it along your flight path until a specific point where you make it disappear out of view in the same tick as using that things to replace it as a real physics object travelling at speed?

P.s. I still think you should add a horizontal force to one wing to make it start spiraling out of control as it crashes That would look so cool :P
