Rotating Bogies and Rotation Control

[Anonymous]

A test version of RtR has been released which includes two new features – rotating bogies and a rotation control, http://brainbombers.com/forum/viewtopic.php?t=569&start=0&postdays=0&postorder=asc&highlight=.

ROTATING BOGIES

Brainbombers will be releasing the capability for modelers to add a rotating bogie feature.

Note the difference between the locomotive and the hopper with its rotated bogies.

The following are preliminary specifications and may change:

Rolling stock developed to make use of this new feature will consist of two models: body and bogie.

The body should be elevated the appropriate distance from the horizontal plane to fit the bogie.

The distance from the center mass of the model to the center point of the bogie will be used to position the bogie fore and aft.

1. This feature requires two consecutive entries in the xli file with body being the first entry. The model numbers are to be an incremented pair. The bogies will be recorded as DUMMY_TYPE.

2. The distance from center mass to center mass will be recorded as the third line of the body entry.

ROTATE CONTROL

The rotate control is another tool for the modeler. This control will permit smooth movement at a defined speed within a defined arc along a defined axis.

Rotation is defined in the rtr_objcontrol*.list file.

The list entry for a model is constructed as such:

10389 ROTATE 2

z-0090d050 Open

z+0090d050 Close

a. model ID number – 10389 (from the xli file)

b. control type must be ‘ROTATE’

c. the number of possible states – 2 in this instance. 3 would be the maximum for the same reason as explained in the blinker control.

d. the axis of movement – z

e. – or + the direction of movement (counterclockwise or clockwise)

f. the arc of movement through a complete 360 degrees – 0090 in this instance.

g. d – required separator between the two sets of numbers

h. speed of rotation. A higher number will result in a faster rotation (degrees per second – if the object rotates a complete 360 degrees with the speed defined as 090, the entire animation will last four seconds).

h. Descriptive text for the action that will be displayed in the control window (no spaces)

The user will be presented with the following screen after placing an object that is capable of being rotated and choosing to control it.

I’ve used the control to reposition the points signal to indicate the turnout is active.

The center of rotation of the model is based on its orientation to x,y,z during the modeling process.

Brainbombers has requested that any questions regarding this particular test release be directed to me.

Hi BB and chris this is great. The ROTATE CONTROL will be great for the things that I think gnome made. Ass hall doors, british Xgates and the turning bridges. Will these work?

[Anonymous]

Hi Dave,

Yes, it should work for any model requiring rotational movement. Doors, crossing gates, and turning bridges should all be perfect applications for this control.

Hay all,

I think this could be as the turntabel but mobile and without any controlerboxes on tracks.

Hi Peter,

The type of rotation, up to three states, is determined by the entries in the appropriate list file. The rotation is triggered by the

Hay Brainbom,

If we do these models with rotating bogies then what id range do we have?

Hi Peter,

Note the xli entries above. The rotating bogie will be dummy_type and the model ID will be the next sequential model number. Otherwise, there are no restrictions on the ID to use.

CWAGON_TYPE 10631 body_test.x 0.37 body

As DUMMY_TYPE, it will not be displayed in the menuing system.

Hope that helps,

Hay Chris,

Then with the animated wheeltrucks i can model “the crocodile E-loco”

2 C´C´2.

Thx for the info Peter

[Anonymous]

Hi Peter,

Just remember that the rotating trucks will be placed in a symmetrical position fore and aft based on the “L” value. So if that’s the case with your loco, you should be golden.

Oh, a thought, if that’s NOT the case for your loco, you could probably shift the model forward or back on its long horizontal axis to fool the program into placing the rotating bogies at the points where you need them.

Chris

Hay Chris,

This loco is symetric,don´t worry.

Chris the object ROTATE CONTROL will this work with the 1.5 that we can Dload? As I would like to have a go at the british X gates that gnome made.

Hi Dave,

No, I doubt that. I was given a newer version of the 1.5 beta to test. (I was warned that layouts saved with it would not be playable under earlier versions of RtR.)

The rotating bogies version is an intermediate release version of the beta as well (between the public release beta and the rotating controls beta).

Regards,

Chris

Hay Chris and Dave,

This beta 1.5 is absolutely newland for us all,self the bogiecontrol is also beta as the soundfunction and the blinkingfeature and the lamplifting. 😉
