FindChild problem
Blitz3D Forums/Blitz3D Programming/FindChild problem
| ||
| I've created a tree in Milkshape with two groups (child entities) called Trunk and Leaves, then exported as a .B3D. So that I can fly, climb, etc through the leaves but bump into the trunk, I want to set the collisions separately: [CODE] parent = LoadAnimMesh("Tree1.b3d") child = FindChild(parent,"Leaves") If child <>0 EntityType child,0 EntityPickMode child,0 EndIf child = FindChild(parent,"Trunk") If child <>0 EntityType child,TYPE_OBJ, False EntityPickMode child,2 ; polygon EndIf [/CODE] But the 'child' variable always returns 0, so they are never set. If I export as a .X file it works! I want to use .B3D if only because the scaling is correct, and for future compatibility. Anyone know what I am doing wrong? |

| purhaps the letters are lowercase or uppercase? (the names of the children)? |
| ||
| Nah, just checked. Case doesn't matter. But just checked, and the .X file contains refs to both LEAVES and TRUNK. The .B3D file contains none. Is this then a problem with Milkshape? But I thought plenty of other people were already manipulating Ms3D>B3D entities (hands etc) or so the forums would have you believe. |

This should tell you all you need to know:parent= LoadAnimMesh("Tree1.b3d")
ent = parent
While ent
Debuglog EntityName(ent)
ent = NextChild(ent)
Wend
;in the code archive
Function NextChild(ent)
If CountChildren(ent)>0
Return GetChild(ent,1)
EndIf
Local foundunused=False
Local foundent = 0, parent,sibling
While foundunused=False And ent<>0
parent = GetParent(ent)
If parent<>0
If CountChildren(parent)>1
If GetChild(parent,CountChildren(parent))<>ent
For siblingcnt = 1 To CountChildren(parent)
sibling = GetChild(parent,siblingcnt)
If sibling=ent
foundunused = True
foundent = GetChild(parent,siblingcnt+1)
EndIf
Next
EndIf
EndIf
EndIf
ent = parent
Wend
Return foundent
End Function

| No, actually. With all due respect and thanks this doesn't help. If the literal child entity names 'TRUNK' and 'LEAVES' are not exported in a Milkshape>B3D then getting the handle of each child entity won't help. I would merely have a list of child entity handles without knowing what I could do with them. Any other ideas? |
| ||
| Sorry, I misunderstood the problem. Are the TRUNK and LEAVES two separate Surfaces in the B3D file? If so, you might have to remove one and rebuild it in its own Entity. |
| ||
| TRUNK and LEAVES are two separate child entities already, but it seems that Milkshape does NOT export the names in a B3D, but DOES export the names in an X file! (-with bad scaling). I'll find a workaround somehow. Thanks for trying to help. But this is getting very tedious. So many people on the forums are wittering on about using GetChild/FindChild to manipulate hands,guns etc so what the hell modeller are they using which preserves the child entity names when exported? And please don't say 3DS Max. Yecchh! |

| I use CharacterFX. Please notify the guys of Umbalum, the maker of Milkshape, or the maker of the B3D export plugin, they might correct this bug, it really seems to be a bug. |
| ||
| send me the tree model and i'll try messing in milkshape with it, i always use milkshape for my exports and never have any trouble so something wrongs going on. |
| ||
| Thanks sinu, it's on its way. Cheers, john. |
| ||
| Sinu, your email address failed. Any other? |

| John, A daft question but no one has asked it asaik - you have the very latest B3D exporter for Milkshape yes? (Well I did say it was a daft question).
