v0.3.0

[brenocq]

The main features added in this version are:

• Infrared sensor #48 An infrared sensor is now available
• Hierarchical prototype #47 Prototypes will now work with entities that have children
• Time profiler #46 It is now possible to profile the code while running to find bottlenecks
• Bullet and box2d physics #45 Improved physics
• Linux compilation #44 Full Linux support

Infrared sensor

The measurement will be done using the physics engine according to the desired ODR and it will be further processed according to the configured parameters.

Profiler Tool

How to use

To profile a function it is only necessary to add PROFILE() at the beginning. For example:

int myFunc(int x, int y) {
    PROFILE();
    return x + y;
}

You can also specify the name yourself by using PROFILE_NAME

void RobotScript::update(cmp::Entity entity, float dt) {
    PROFILE_NAME("RobotScript::update(" + std::to_string(entity.getId()) + ")");
    // ...
}

Time Profiler window

Can be found in Tools>Time Profiler.

Hierarchical prototypes

Now it is possible to have prototypes with children, this way more complex prototypes can be achieved (e.g. robots with multiple sensors).
