Draw

Defined in Draw.hpp. All drawing functions are in the xenon::Draw namespace. Call these from on_render().

Line

void Draw::Line(float x1, float y1, float x2, float y2, Color color, float thickness = 1.f);
void Draw::Line(const Vector2& start, const Vector2& end, Color color, float thickness = 1.f);

Draws a line between two points.

Parameter	Type	Description
x1, y1	float	Start point
x2, y2	float	End point
color	Color	Line color
thickness	float	Line width in pixels (default: 1)

Draw::Line(100, 100, 200, 200, Color::Red());
Draw::Line(screenCenter, targetPos, Color::White(), 2.f);

---

Circle

void Draw::Circle(float x, float y, float radius, Color color, float thickness = 1.f);
void Draw::Circle(const Vector2& center, float radius, Color color, float thickness = 1.f);

Draws a circle outline.

Parameter	Type	Description
x, y	float	Center position
radius	float	Radius in pixels
color	Color	Circle color
thickness	float	Line width (default: 1)

Draw::Circle(500, 500, 50, Color::Green());

---

CircleFilled

void Draw::CircleFilled(float x, float y, float radius, Color color);
void Draw::CircleFilled(const Vector2& center, float radius, Color color);

Draws a filled circle.

Parameter	Type	Description
x, y	float	Center position
radius	float	Radius in pixels
color	Color	Fill color

Draw::CircleFilled(headScreen, 5.f, Color::Red());

---

Rect

void Draw::Rect(float x, float y, float w, float h, Color color, float thickness = 1.f);
void Draw::Rect(const Vector2& pos, const Vector2& size, Color color, float thickness = 1.f);

Draws a rectangle outline.

Parameter	Type	Description
x, y	float	Top-left corner
w, h	float	Width and height
color	Color	Border color
thickness	float	Line width (default: 1)

Draw::Rect(100, 300, 200, 100, Color::White());

---

RectFilled

void Draw::RectFilled(float x, float y, float w, float h, Color color);
void Draw::RectFilled(const Vector2& pos, const Vector2& size, Color color);

Draws a filled rectangle.

Parameter	Type	Description
x, y	float	Top-left corner
w, h	float	Width and height
color	Color	Fill color

Draw::RectFilled(100, 500, 200, 100, Color(0, 0, 0, 128));

---

Text

void Draw::Text(float x, float y, Color color, const char* text, int size = 0);
void Draw::Text(const Vector2& pos, Color color, const char* text, int size = 0);

Draws text at the specified position.

Parameter	Type	Description
x, y	float	Top-left position
color	Color	Text color
text	const char*	The text string
size	int	Font size (0 = default)

Draw::Text(100, 700, Color::White(), "Hello World");
Draw::Text(headScreen, Color::Yellow(), "Enemy", 16);

---

HealthBar

void Draw::HealthBar(float x, float y, float width, float height, float healthPercent,
                     Color bgColor = Color(50, 50, 50),
                     Color healthColor = Color::Green(),
                     Color borderColor = Color::White());

Draws a health bar with automatic color gradient (green at full, red at empty).

Parameter	Type	Default	Description
x, y	float	—	Top-left position
width	float	—	Bar width
height	float	—	Bar height
healthPercent	float	—	Health percentage (0-100)
bgColor	Color	(50, 50, 50)	Background color
healthColor	Color	Green	(Unused — color is auto-computed from percentage)
borderColor	Color	White	Border color

float hp = enemy.GetHealthPercent();
Draw::HealthBar(headScreen.x - 25, headScreen.y + 10, 50, 4, hp);

Unused parameter

The healthColor parameter is accepted for API compatibility but currently ignored. The fill color is automatically computed from healthPercent: green at 100%, yellow at 50%, red at 0%. You can safely omit it:

// These produce identical results:
Draw::HealthBar(x, y, 50, 4, hp);
Draw::HealthBar(x, y, 50, 4, hp, Color(50, 50, 50), Color::Green(), Color::White());

---

TextShadow

void Draw::TextShadow(float x, float y, Color color, const char* text, int size = 0, Color shadowColor = Color::Black());
void Draw::TextShadow(const Vector2& pos, Color color, const char* text, int size = 0, Color shadowColor = Color::Black());

Draws text with a 1-pixel offset shadow for readability. The shadow inherits the text's alpha.

Parameter	Type	Default	Description
x, y	float	—	Text position
color	Color	—	Text color
text	const char*	—	Text string
size	int	0	Font size (0 = default)
shadowColor	Color	Black	Shadow color (alpha is overridden by text's alpha)

Draw::TextShadow(100, 100, Color::White(), "Readable text");

---

TextCentered

void Draw::TextCentered(float x, float y, Color color, const char* text, int size = 0, Color shadowColor = Color::Black());
void Draw::TextCentered(const Vector2& pos, Color color, const char* text, int size = 0, Color shadowColor = Color::Black());

Draws roughly centered text with a shadow. Centers by offsetting strlen(text) * 3 pixels to the left.

Parameter	Type	Default	Description
x, y	float	—	Center position
color	Color	—	Text color
text	const char*	—	Text string
size	int	0	Font size (0 = default)
shadowColor	Color	Black	Shadow color

Draw::TextCentered(screenCenter.x, boxTop - 15, Color::White(), "Enemy Name");

Note

Centering is approximate since the default font is not monospaced at all sizes. Works well for the default font size.

RectCorners

void Draw::RectCorners(float x, float y, float w, float h, Color color, float thickness = 1.5f);
void Draw::RectCorners(const Vector2& pos, const Vector2& size, Color color, float thickness = 1.5f);

Draws corner bracket marks (25% of each edge) instead of a full rectangle. Common for tactical/military-style ESP bounding boxes.

Parameter	Type	Default	Description
x, y	float	—	Top-left corner
w, h	float	—	Width and height
color	Color	—	Line color
thickness	float	1.5	Line thickness

Draw::RectCorners(minX, minY, maxX - minX, maxY - minY, Color::White(), 1.5f);
