Gamedev Utils (by Konstantin Tomashevich)

My personal archive of useful small C++ libraries for gamedev projects. Supports SDK and CMake target export throught install command.

GraphPathfinding

No dependencies.

Dijkstra and A* pathfinding algorithms. Input graph must implement GraphAdapter interface.

HexagonalGrids

Dependencies: GraphPathfinding, SharedPointer, UniversalException, Urho3D (only for example), Urho3DDebugCamera (only for example).

Implementation of doubled coords hexagonal map (double-row-coord and double-col-coord). Supports pathfinding and custom cell metadata. In addition, there is simple Urho3D example app.

WASD - move camera, QE -- rotate camera, LMB -- teleport ball, RMB -- try navigate to cell.

QuestStateMachine

Dependencies: SharedPointer, UniversalException.

Simple state machine for dialogs and quests. See simple console calculator example which emulates dialog on this machine.

SharedPointer

No dependencies.

Simple shared pointer for ReferenceCounted derived classes.

UniversalException

No dependencies.

Simple exception class that works both on Visual C++ and GCC. Also it supports "custom" exceptions (see QuestStateMachine for example).

Urho3DActivitiesApplication

Dependencies: Urho3D, UniversalException.

ActivitesApplication is useful for splitting game to 2 parallel activities like client and server in the same process. Also ModularActivity is something like local (for this activity) version of Urho3D::Context which is useful in some cases.

Urho3DDebugCamera

Dependencies: Urho3D, UniversalException.

Two simple camera handlers useful for prototyping. See Urho3DHexagonalGrids (HexagonalGrids example) as example.

Urho3DUIResizer

Dependencies: Urho3D.

Urho3D component for Urho3D::UIElements resizing and layouting. Used Urho3D::UIElement vars:

For position calculation:

VX : float, X-coord modifier.

VY : float, X-coord modifier.

XDep : String, dependency for X-coord, value: "SH" (Screen Height), "SW" (Screen Width), "PW" (Parent Width), "PH" (ParentHeight).

YDep : String, dependency for Y-coord, value: "SH" (Screen Height), "SW" (Screen Width), "PW" (Parent Width), "PH" (ParentHeight).

Result X = VX * value (XDep)

Result Y = VY * value (YDep)

For size calculation:

VWidth : float, width modifier.

VHeight : float, height modifier.

WDep : String, dependency for width, value: "SH" (Screen Height), "SW" (Screen Width), "PW" (Parent Width), "PH" (ParentHeight).

HDep : String, dependency for height, value: "SH" (Screen Height), "SW" (Screen Width), "PW" (Parent Width), "PH" (ParentHeight).

Result Width = VX * value (XDep)

Result Height = VY * value (YDep)

For layouting:

LayoutType : String, "H" (Horizontal) or "V" (Vertical) or nothing (no layouting).

UpdatePS : bool, if true, primary size will be calculated from children size.

UpdateSS : bool, if true, secondary size will be calculated from children size.

Also Layout Border and Layout Spacing of Urho3D::UIElement are used too (result is 0.001 * value (dep) where dep is HDep or WDep depending on layout type).

For texts (Urho3D::Text and Urho3D::LineEdit only):

VTextSize : float, text size modifier.

TSDep : String, dependency for test size, value: "SH" (Screen Height), "SW" (Screen Width), "PW" (Parent Width), "PH" (ParentHeight).

Result Text Size = VTextSize * value (TSDep)
