TFormVector??? Why wont it work?

[Andy Gilbert]

Hi.. does anyone know why the Vector will not stay local in this command?

 

mesh1:AddForceAtPoint(TFormVector(Vec3(0,Force,0),null,mesh1),TFormPoint(Vec3(0,0,2),null,mesh1))

 

It starts fine, but as soon as it turns on a different axis, its clear the force is not acting relative any more.

 

Thanks

I assume you want it local relative the mesh1 entity?

[Andy Gilbert]

Hi tyler, yes thats right, i want to add a force at a point on my model, thats allways relative in position and rotation of the model, mesh1.

 

Thanks

It may be messing up if that is a mesh and not a model. Try using it on the parent of mesh1. (Passing mesh1.parent or whatever to the TForm... functions)

Doesnt seem to be that ,so this is still unknown... I have tried it on mesh's, bodies?

 

Just cant seem to get it to work?

mesh1:AddForceAtPoint(TFormVector(Vec3(0,Force,0),null,mesh1),TFormPoint(Vec3(0,0,2),null,mesh1))

 

1. You can't add forces to a mesh, only a body or a model.

2. Is Force a float value or a Vec3 itself?

3. In Lua you use nil, not null.

4. AddForceAtPoint is global, so I am not sure why you are transforming the point and force to local space to begin with.

Hi Josh.. Ok ill answer the easiest.

 

1.You can't add forces to a mesh, only a body or a model.

I know that, and i am adding to a body, it was just a name i was using.

2.Is Force a float value or a Vec3 itself?

Im not to sure what you mean by that, but basically i have a variable which is a float that im using as my force in a Vec3.

3.In Lua you use nil, not null.

Ok, ill change that, it compiles fine so i didnt know any other.

4.AddForceAtPoint is global, so I am not sure why you are transforming the point and force to local space to begin with.

My originally question may answer that ( But basically because i want them local, not global)

All, i want to do is add a force at a point on a body, and that force and position of it stay LOCAL to the body.

 

Thanks

Oh!

 

Since AddForceAtPoint is a global function, and the force and such you are adding is Local, you need to transform from the body's local space into global space. Switch nil and mesh1 positioning in the Transform command so mesh1 is first and nil is second, which should work properly
