New function in animator

[GateGirl86]

like someone who has never driven a manual car before, you know, when they don't clutch it properly. That is just the movement. When I run it, it just disappears off the screen.

So, as I said before, 55m in 1min 16 seconds before turning. I think as the Video starts, it should sit there for at least 2 seconds.

[Support]

I know what you mean. Can you send me a screen shot?

ok, so you want it to sit there at the start of the video for 2 seconds then, you want it to start going for 1 minute and 16 seconds and travel a total of 55 meters?

[GateGirl86]

A screen shot of the start? Or an empty airfield when it disappears?

exactly that!

I do have a question though. What if I wanted to say, once it's arrived at the pause spot after turning, then sits waiting to take off. I wanted to change the camera angle to a side view and see it move down the runway from the starboard side?

a screen shot of the whole Raylectron window.

ok, but you're going way ahead, so lets start with the 55m run first.

py := Accelerate(0.0157, meters, 2, 78);

the 78 is 1 min 16 sec + the 2 seconds offset for the start.

I'll try that, thank you.

I don't know what is wrong, the measurement is correct according to the SKP measure tool, yet its still going off screen to the right?

[Support]

Looks fine in the Window.

Can you step it using the forward button? the one to the right of the stop button and see how much it moves per frame.

oh, but it's normal that it still goes forever since we didn't start a new event to stop it!

[Support]

But does it starts ok until the point where it needs to turn?

I've modified the engine so it's even easier. Download and install the new RBX, no need to re-export from Sketchup, just load back your ROF file.

Next post I'll explain...

So I've added the variable Units so you can set the units at the beginning of the code rather than always including it in the functions. So the very first line of code for you should be...

Units := Meters;

Now, I've created a new function that calculate the acceleration based on distance and time. Si from a stand still, if you want your 302 to move 55m in 76 sec, use the following to compute the acceleration...

acc := ComputeAcceleration(55, 76);

now you can use 'acc' in the Accelerate function...

py := Accelerate(acc, 2, 78);

so now let me ask for the second task, we have it accelerate for 76 sec but, don't we need to decelerate it before it starts to turn? So now, tell me when you want it to decelerate how the distance it will come to a stop. We will then change the timing of the first even.

I'm totally buggered Michael. I haven't slept properly for days, as I've been doing multiple shifts. Right now I can barely see the screen, so I need to give this a break for a while. I did however send you the SKP file.

[Support]

oh, take care of yourself now, and don't feel obligated to reply or anything, I'm not pressuring you in any ways.

[GateGirl86]

I managed to get some sleep. And since I don't have a shift now until 12 midday, other than a little more sleep, I can manage this I think.

I'd like to ask though Michael if you could give me a head start and write the first lines for me, from the start to the turning point. So that I am able to more understand how it functions.
At between 5 and 8 kmh, the taxiing speed, a fighter doesn't perceptibly slow down to make the turn.

[Support]

You need to take it easy and have some rest. I'm working on a new set of functions that will make it way easier for you. Maybe tomorrow if you're up to it?

[GateGirl86]

I should be much more awake tomorrow, thank you Michael. I did add that new RBZ by the way.

[Support]

I hope you rested good and if you're up to it and have time, here is something that should work and here is a video to show it, the runway is 55m till the start of the other runway. But first, download and install the new RBZ...

https://raylectron.com/files/Raylectron.rbz

and here is the script, we'll talk about it when you run it and see what it does...

Code: Select all

Units := Meters;

Distance := 40.0;
Duration := 25.0;
StartAt  := 2.0;
EndAt    := Duration + StartAt;
py := Velocity(0, Distance, StartAt, EndAt);

Distance2 := 25.0;
Duration2 := 20.0;
StartAt2  := EndAt;
EndAt2    := Duration2 + StartAt2;
if (sec >= StartAt2) and (sec <= EndAt2) then begin
  d := Velocity(0, Distance2, StartAt2, EndAt2);
  py := py - d;
end;

TurnAngle := -90.0;
Duration3 := 10.0;
StartAt3  := EndAt2 - 17;
EndAt3    := Duration3 + StartAt3;
Yaw(TurnAngle, StartAt3, EndAt3);

if (sec >= EndAt2) then
  py := 0;

I will have some time later this morning. And I am feeling much brighter, thank you so much Michael.

And that is fantastic!

[GateGirl86]

27 hours 15 mins. Which is far, far better than 100+ hours

[Support]

You mean video make time?

[GateGirl86]

Yes, and weirdly, it has gone up t0 28 hours, rather than down.

[Support]

That can happen, it depends on the current view, if there are more reflections exposed for example.

[GateGirl86]

Such as water?
