ToolResponse begin(const ToolArgs &args) override
Gets called right after the constructor has finished.
Definition: tool_add_vertex.cpp:27
bool can_begin() override
Definition: tool_add_vertex.cpp:8
bool is_specific() override
Definition: tool_add_vertex.hpp:13
ToolResponse update(const ToolArgs &args) override
Gets called whenever the user generated some sort of input.
Definition: tool_add_vertex.cpp:59
This is what a Tool receives when the user did something.
Definition: tool_pub.hpp:23
Common interface for all Tools.
Definition: tool_pub.hpp:94
Definition: tool_helper_plane.hpp:5
To signal back to the core what the Tool did, a Tool returns a ToolResponse.
