textureId

Texture IDs can be explicitly converted to integers, but not the other way around. You can add and subtract integers with a textureId, however. (This only works with the integer on the right hand side.)

Instance Methods

bool Exists() const

Checks if the texture exists within the texture manager at all.

bool IsNull() const

Checks if the texture is the null index 0.

bool IsValid() const

Checks if the texture index is not the invalid index -1.

void SetInvalid()

Sets the texture index to -1.

void SetNull()

Sets the texture index to 0.

Zero-Initializing

The proper way to zero-initialize a textureId is:

textureId tex;
tex.SetNull();
