UMA Calculate Head Collider at Runtime
Hi guys,
i'm woundering how i could calculate the head collider for a UMA Char at Runtime.
A Capsule collider for the whole avatar is easy done but is there an way to seperate the body height and the head ?
THanks in advice!
hello, i have never used uma but maybe i can help you. why are you havinig issues getting the head collider?, what do you mean by calculate, get the radious? it is a mesh collider? can you share a screen shot of the collider from the inspector?
you can attach a collider to each part of te body and check separate damage on the parent body script when a collider send the OnCollisionEnter to the MonoBehaviours also sent it to all the parent's MonoBehaviours on hierachy, so from a common parent you can manage the the collisions on all their children, by example on the UMA parent, you can manage all the collision to the child parts:
void OnCollisionEnter(Collision collision)
{
foreach (ContactPoint contact in collision.contacts)
{
if(contact.thisCollider.CompareTag("head")){
//add damage to head here
splashBlood (contact.point);
}
if(contact.thisCollider.CompareTag("torso")){
//add damage to torso here
splashBlood (contact.point);
}
if(contact.thisCollider.CompareTag("limb")){
//add damage to limbs of body here
splashBlood (contact.point);
}
}
}
if you cant attach a child with a collider (by example a tank with a weak point without external/child mobile parts) you can determine the position of he "weak point" by math: lets supposed that the weak point is 1.5 units above the center and have a radius of 0.3 (like the head is above of torso, or a turret above the tank...)
void OnCollisionEnter(Collision collision)
{
foreach (ContactPoint contact in collision.contacts)
{
if(contact.thisCollider.CompareTag("Tank")){
//calculate the headpos in global space
Vector3 headPos = transform.position + transform.up*1.5f;
//check if the contact was close to the weak point (inside the weak area)
if((contact.point - headpos).sqrMagnitude < 0.3*0.3){
//add damage to head here
}else{
//add damage to the rest of the tank here
}
addDecal (contact.point);
}
}
}
Hi,
thanks for your answer, but thats not that what i need, i need to create the colliders at runtime at the U$$anonymous$$A Character-
U$$anonymous$$A is creating one complete $$anonymous$$esh, its not seperated in head and body thats why its get tricky.
you can use the AddComponent to add a sphere collider at the head position, that doesnt work?
Would work, but how to get the head position?
yep, a single mesh, but the old U$$anonymous$$A had a child gameObject for each bone modifier of the mesh, who can be modified attaching a collider to each one, that was modified? sorry I dont use that since a year
ahh you mean i should create them on the bones?

I'm working at a online U$$anonymous$$A integration, i have to put many scripts at the main U$$anonymous$$A char (liek char controller, health, etc pp) and i render the bones in the editor cause i have to put some scripts before the main object get active, otherwise i dont get them right in sync.
is there an way to recalculate the bones at runtime? so dont delete and add them again, just set the correct size and posision?
