[Character controller collision fall through floor (Project included)]

Hi Josh,

 

I've just done a quick project to show the first of my character controller issues.

 

The character controller goes through walls floors at higher velocities. In this demo the higher the character falls, the more he passes through the floor.

 

Cheers

 

 

[Editor sound node]

Just did a quick one if anyone is interested. Just add it to a Pivot or some other node.

 

 

[Editor sound node]

Is there currently any way to add a sound node into the level editor? I understand I could create a quick lua script, but Is there an official way?

Hi neseir,

 

Ok I purchased a sensor and the Fastmocap program. I played around for a very short time capturing animaions in fastmocap.

 

The room I did it in was not 100% ideal so that is a factor in this. Fastmocap appeared to capture animations ok. HOWEVER, when I exported to character studio the animations were all garbled every time and could not get it to work. I lodged a support case with them around 5 days about this and haven't heard back. So not happy at all with Fastmocap currently and wouldn't recommend it to date, hopefully it can change my mind. A tutorial would be nice on the import process.

 

Brekel worked a lot nicer and is more feature packed than Fastmocap, animations came through a bit funny in Max also (distorting bones), but better than Fastmocap. Maybe I'm missing something on the import?

 

I can't test any other exports for any other program program.

 

Let me know how you go with your tests.

[Character controller : throught floor and walls]

Hi Josh,

 

Don't forget I messaged you a link download to my project which shows many character controller physic issues. The title of the message is "Project"

 

Cheers!

[one shot animation]

Hi Cassius

 

Here is something Ive adapted from the lua code...

 

void GameCharacter::SetAnimationSequence(float blendTime)
{
blendStart = Time::GetCurrent();

blendFinish = blendStart + blendTime;
}

 

 

 

if(characterState != prevCharacterState)
{
SetAnimationSequence(500); //This only gets hit once.
}

sequence = 1; // or whatever

float animSpeed = 0.04F;
float blend = (Time::GetCurrent() - blendStart) / (blendFinish - blendStart);

blend = Math::Min(1.0, blend);
frame = (Time::GetCurrent() - blendStart) * animSpeed;

float length = entity->GetAnimationLength(sequence, true);

if(frame >= (length - 1))
{
frame = length -1;

characterState = kStateIdle;
}

entity->SetAnimationFrame(frame, blend, sequence, true);

 

Hope this helps

[Specular on full]

It worked for me, have you added a specular map and played around with the specular values in the material editor? (after you added shadmar's fixes)

[Jump and physics :]

Hi YouGroove

 

In the Entities SetInput(-character->GetYaw(), character->GetMove(), 0.0F, character->GetJump(), 0.8, 0.8)

 

Its for 4th parameter which applies a jump force. I've set it on a timer so the force is applied for a fraction of a second when you hit a key.

 

hope this helps.

[Motion tracker]

Hi Neseir, I couldn't help myself and purchased fastmocap. The software seems ok, I've tried to export out to biped bvh and it produced garbage for the biped animation although played as captured in their software. It's too early to sledge them yet, I really haven't had much time to play, and haven't had a response back about the export issues. I'll keep you posted.

[Motion tracker]

Right, so I picked up an XBox Kinect with power supply and I tested it last night with Brekel (the setup was very easy). It was only a quick test as the room I tested in had too much visual noise and I couldn't position it very well on the desk (It tried to pick up the book case as a user lol).

 

Anyway it did pickup me and created a skeleton from it and seemed to handle movement quite well. I haven't exported any animations yet and I'm going to set something up a bit more appropriate in the back shed so It can pick movement up better.

 

I must say this does have the potential to be a real time saver, not to mention better and more fluent results. I understand that there will be the need for manual editing, but it will provide a nice base animation for you to tweak.

 

I'm considering buying fast mocap as it looks quite a nice piece of software, we shall see.

[High Roller Unfinished.]

Hi Andy

 

 

Try this in your entities physics update to keep it on the z axis...

 

Vec3 pos = entity->GetPosition();

 

pos.x = 0.0F;

 

entity->PhysicsSetPosition(pos.x, pos.y, pos.z, 0.01F);

 

 

This works on all physics apart from a character controller, I still haven't found a way to restrict an axis for a character.

[EmitSound() issues]

I have created an entity, and called it's member EmitSound(sound)

 

 

The emitted sound plays however it does not follow the entity that called it and remains stays at it's creation point. Setting the sound to loop is a good test.

 

Also

 

Set the Draw stats to 1.

 

keep emitting a sound.

 

Watch your memory usage go up and up. It says in the doc's the sound is supposed to be released after playing, but it doesn't look like it's happening to me. Memory usage goes up with the Play() function too.

 

Cheers!

[Tree Modeling with Forester Pro]

What I do with tree[d] is create very large leaves and fewer of them and apply the branch texture.

 

To create branches I create a tree in tree[d] and render it out as a branch.

Thanks tournamentdan

While were on the topic does anyone have any experience with mocap with a Kinect sensor?

 

http://www.fastmocap.com/

 

If it's any good, you could potentially create some semi decent mocap animations for around the $300 - $500 mark. Obviously it's not going to do the job like in a pro studio, but if it could give you a good head start it may be worth it.....

 

I'm almost considering trying out the fastmocap and picking up a sensor......

 

Any thoughts before I blindly spend the cash?

Invert the Y channel on the normal map texture?

Hi yes,

 

They are under the Objects tab then select Effects from the first drop down. After that you can then add them to the scene.

Hi Josh,

 

Just want to confirm you have downloaded the project? I want to remove it that's all.

[Sound debug vs release]

Hi Rick,

 

Was having the same issue when compiling in release for my project, debug is fine for sounds. It's pointing to a bug imo.

[Collision type property]

Hmm no idea if it works in Lua. Good Luck!

[Collision type property]

enum

{

 

kCollisionProjectile = 6,

kCollisionEnemyAI = 7,

kCollisionCorpse = 8

};

 

PhysicsDriver::GetCurrent()->SetCollisionResponse(kCollisionProjectile, Collision::Scene, 1);

PhysicsDriver::GetCurrent()->SetCollisionResponse(kCollisionProjectile, Collision::Prop, 1);

PhysicsDriver::GetCurrent()->SetCollisionResponse(kCollisionProjectile, kCollisionEnemyAI, 1);

PhysicsDriver::GetCurrent()->SetCollisionResponse(kCollisionProjectile, Collision::Trigger, 0);

PhysicsDriver::GetCurrent()->SetCollisionResponse(kCollisionProjectile, Collision::Character, 0);

PhysicsDriver::GetCurrent()->SetCollisionResponse(kCollisionProjectile, kCollisionProjectile, 0);

 

done =)

[shoot with physics]

Hi Rick

 

This does it it's pretty much a cut and paste from my code so just let me know if you need any help as some bit's wont make sense. I also created a custom collision type too if you are wondering....

 

//Get the projectile direction

Mat4 matrix = character->GetTargetEntity()->GetMatrix();

 

projectileVelocity = character->GetTargetEntity()->GetMatrix()[2].xyz() * 900;

 

 

 

//Create the bulllet

 

Shape* shape = Shape::Box(0.0F, 0.0F, 0.0F, 0.0F, 0.0F, 0.0F, 0.1F, 0.1F);

GetTargetEntity()->SetShape(shape);

shape->Release();

 

 

GetTargetEntity()->SetPhysicsMode(Entity::RigidBodyPhysics);

 

GetTargetEntity()->SetMass(1);

 

GetTargetEntity()->SetCollisionType(kCollisionProjectile);

 

GetTargetEntity()->SetGravityMode(0);

 

GetTargetEntity()->AddForce(projectileVelocity);

 

GetTargetEntity()->AddHook(Entity::CollisionHook, (void*)ProjectileCollisionHook);

 

GetTargetEntity()->AddHook(Entity::UpdatePhysicsHook, (void*)ProjectilePhysicsHook);

 

Hope this helps!

[Character Controller Jump issue 2]

Hi YouGroove,

 

It dosen't work properly for the Character yet sohe can be bumped right off can't find a suitable 100% solution to it. Using PhysicsSetPosition works for everything except the Character Physics.

[Character Controller Jump issue 2]

Can do,

 

I'll provide you with a link later when I get home. Feel free to fix any of my bugs while you are at it =).
