Hi there,
perhaps anybody can help me with this:
I’m trying to setup a basic controller for my animated characters. But I can’t figure out how blending with multiple layers works correctly.
The Setup: my character should use several weapon types, so he has several animation sets (e.g. one for pistols and one for rifles). These animations should be blended over the walk, run, jump animations. Walk, run, etc. are on the base layer.
Layer 2 has a body mask for the torso and the arms. On that layer are animations like aim and fire, because for that the upper torso has to be turned right, so that the character aims to the crosshair (3rd person).
Layer 3 has a body mask only for the arms. All animations that only affect the arms and not the torso are on that layer (holding a 2 handed weapon or reload).
My character should do the following:
- If he has a rifle, he should hold it in idle, walk, run, etc. That means base layer + layer3.
- If I now press and hold the RMB he should go into the aim position = base layer + layer2.
- If now the RMB is released he should return to no.1 = base layer + layer3
The problem:
No.1. and 2. are working as intended, but when the RMB is released the torso stays in the turned right position, so the torso still aims to the crosshair. The arms go into the holding position again.
It seems that the upper torso didn’t get the weight of the base layer again (the weight of the torso bones from the idle animation) – and I don’t know why.
Take a look at the pic below or my pretty crappy code. One thing to say: I’m not a programmer, only a 3d artist, therefore I would appreciate if you can post some code if you know where I failed.
I think the following lines are important for the layer blending (but I can be wrong and there is something else I missed):
27 – 29 references to the states of the animator
67 – 71 Setting the layer weight according to the layer count
85 – 91 Setting layer state variables to the current state of the layers.
289 – 319 my code that should control the behavior.
Thx for your help.
