Cant append vector in map

[a.koryakin]

Hi All
       
I'm rtying to add vector in map like this:

int Events[] ; 
Events.append(ivec3(1,1,1));

Events.append(ivec3(2,2,2)); // this vector was added 
Events.append(ivec3(2,3,4)); // this vector was not added 

log.message(" size = %i  \n", Events.size());

message:
 size = 2

What am i doing wrong? i want to add all three vectors.

Hi Alexander,

 

If you want to fill map with key and value you can try to use append(key, value) method:

Events.append(1, ivec3(1,1,1));
Events.append(2, ivec3(2,2,2)); 
Events.append(3, ivec3(2,3,4));

We will also investigate further your use-case. Probably, there is some incorrect behavior appears.

 

Thanks!

The point is i want to use ivec3 as a key for map

Events.append(ivec3(1,1,1), 1);

Events.append(ivec3(2,2,2), 2);
Events.append(ivec3(2,3,4), 3);

Documentation says i can use variable type as a key and ivec3 is a variable

• void append(variable key)
• void append(variable key, variable value)

Hi Alexander,
 

It seems the there is small bug in Mathlib. It was already fixed in our internal builds.

 

The bug fix will be available in the next SDK update.

 

Sorry for the inconvenience caused.

Hi Alexander,

 

A small update. We are deeply sorry, but mentioned before fix will not be included in the next SDK update.

 

Unigine Map container internally uses binary tree to add elements into it, so the comparison operator is required for all kind of objects that should be added into this Map. Unfortunately, there is no correct way to compare vectors, so you can override "<" method for vector in UnigineScript code and write some custom vector compare logic:

class OurMapCompontent {
    int x;
    int y;
    int z;

    OurMapCompontent(ivec3 vector) {
        x = vector.x;
        y = vector.y;
        z = vector.z;
    }

    int operator<(OurMapCompontent other) {

        // Your comprasion code for vector
        // ...
    }
};

Sorry for the incovenience caused.
