Import egg Files

[steffen]

Hey everyone,

because we are allowed to use egg files from the alice gallery I hope some of you had the same problem and can help me with this one.

When I'm loading a model in the Panda Viewer (pview) e.g. Barn.egg (from the Farm section), the whole building is torn apart. I think there is a mix up with the coordinates of the different pieces of the model. Can someone tell me how I can fix this? I attached a screenshot of the displayed barn.egg, so you can see what I'm writing about.

Thank you in advance

Hey guys, that was the answer (it works):

Hi Steffen,

This is very strange!

The mixup only seems to be a matter of vertical translation for the red outer walls (needs to come down) and the gray roof (needs to go up). Otherwise it is fine.

One possibility to fix this in the Panda code is to get a NodePath to the individual parts of the model that you want to change and call setPos(x,y,z) on those. To get the NodePath, you can use the “find” method on the root of the model, just like when you found the screen on the TV in one of the Labs. To find the names of the different parts of the model, just open the “egg” file and look at the names of the different <Group>s.

Note that you can translate a NodePath node relative to its current position, e.g. for moving it upwards without knowing where it currently sits. You do that by passing a NodePath as an argument to setPos, so in this case if for example RoofNP is your NodePath, you can call RoofNP.setPos(RoofNP, 0, 0, 5) to move the roof upwards.

Hope this helps, let me know how it goes.

Cheers,
