How to measure the distance between two objects in real-time

[Plod]

[ FlexSim 23.1.3 ]

Hello

As the title, when I run a kinematic, I want to get distance between two objects in real-time, sometimes maybe the object is a line or cube, so that is the problem.

best wishes

Hi @Orry,

This post may be helpful. https://answers.flexsim.com/questions/79893/distance-between-two-objects.html

Can you post your model?

For two objects : obj1 and obj2

Vec3 centres=Vec3(0.5,0.5,0.5); // set up centre factors for the axes
updatelocations(obj1);  // in case they are moving
updatelocations(obj2);
Vec3 locDiff=obj1.getLocation(centres).project(obj1.up,model())-obj2.getLocation(centres).project(obj2.up,model());   // projecting onto the model in case they are in different containers/coordinate systems
double distance=locDiff.magnitude;

Thank you, I'll try it later

Ok, thanks for you reply

You can also use more vector operations to define a line and then the shortest distance of an object to it.

Sorry, does the vector means x, y, z axis? I don't know much about this

Yes - here's the Vec3 documenation.

Hello

I use your code in my model, but when run, the text will be invisible, how can I fix it?

Thanks

You need this:

textnode.value=string.fromNum(distance,2);
