NGN_TEXTURE.H

Method

NGN_Texture(
    NGN_TextureData* texture,                   // Object of the TextureData class
    int32_t position_x = DEFAULT_VALUE,         // Initial X position (hidden by default)
    int32_t position_y = DEFAULT_VALUE,         // Initial Y position (hidden by default)
    uint32_t texture_width = DEFAULT_VALUE,     // Texture width (default: width of the texture)
    uint32_t texture_height = DEFAULT_VALUE,    // Texture height (default: height of the texture)
);

Description

Creates a new texture using the previously loaded data.

Example

NGN_Texture* clouds = new NGN_Texture(clouds_gfx, 0, 0);

Method

NGN_Texture(
    uint32_t texture_width,                     // Texture width
    uint32_t texture_height,                    // Texture height
    int32_t position_x = NGN_DEFAULT_VALUE,     // Initial X position (hidden by default)
    int32_t position_y = NGN_DEFAULT_VALUE      // Initial Y position (hidden by default)
);

Description

Creates a new blank texture with the specified size.

Example

NGN_Texture* surface = new NGN_Texture(1280, 720, 0, 0);

Method

void Position(float position_x, float position_y);
void Position(Vector2 pos);

Description

Positions the texture at the given coordinates.

Example

clouds->Position(1200, 900);

Method

void Translate(float speed_x, float speed_y);
void Translate(Vector2 spd);

Description

Moves the texture in the direction and at the speeds provided.

Example

clouds->Translate(5.0f, 0.0f);

Method

void Size(float w, float h);

Description

Resizes the texture.

Example

clouds->Size(64, 48);

Method

void Scale(float w, float h);
void Scale(float scale);

Description

Scales the texture by the given factor. Depending on the overload used, it will scale the axes together or separately. The default scale is 1.0f.

Example

clouds->Scale(1.5f);
clouds->Scale(2.0f, 0.75f);

Method

void Rotate(double degrees);

Description

The texture rotates the provided number of degrees.

Example

clouds->Rotate(1.2f);

Method

void SetCenter(float x, float y);

Description

Specifies, in relative coordinates and from the actual center of the texture, where the rotation center of the texture will be located.

Example

clouds->SetCenter(-10, -5);

Method

void ClearContent (uint32_t rgba = 0x00000000);

Description

Clears the content of a texture if it has been created as blank. If a fill color in RGBA format is not specified, the texture is cleared using the transparent color.

Example

clouds->ClearContent();

Method

void SetTintColor(uint8_t r = 0xFF, uint8_t g = 0xFF, uint8_t b = 0xFF);

Description

Sets a tint color that will be applied to the texture. A white tint (255, 255, 255) will display the texture with its original unaltered colors.

Example

clouds->SetTintColor(96, 255, 192);

Property

Vector2 position
Vector2 screen

Description

Texture position (global or on the screen).

Property

float width
float height

Description

Texture size.

Property

bool visible

Description

Indicates whether the texture is visible or not.

Property

int32_t alpha

Description

Transparency level of the texture, ranging from 0 to 255.

Property

SDL_BlendMode blend_mode

Description

Color blending mode of the texture. Available modes are: NGN_BLENDMODE_NONE, NGN_BLENDMODE_ALPHA, NGN_BLENDMODE_ADDITIVE, and NGN_BLENDMODE_MODULATE. The default value for this property is NGN_BLENDMODE_ALPHA.

Property

double rotation

Description

Rotation of the texture, in degrees.

Property

bool flip_h
bool flip_v

Description

Vertical and horizontal flipping of the texture.

Property

bool ignore_camera_tint

Description

Indicates whether the texture should ignore the tint color assigned to the camera layer.
