API:DynamicImageHasTexture

UI Lua API · DynamicImage functions
Version: WAR 1.4.8

Returns whether a DynamicImage has a usable texture.

hasTexture = DynamicImageHasTexture(imageName)

Arguments

imageName

string – Name of a DynamicImage window.

Returns

hasTexture

boolean – true if the image has a texture.

Details

• Once the image has loaded its texture, the result tells whether that load produced a texture.
• Before that, the client looks the image's texture name up and returns true if a texture with that name is found.
• Both error messages name DynamicImageSetRotation instead of DynamicImageHasTexture.

Errors

• Error in function call 'DynamicImageSetRotation': Window %s does not exist
• Error in function call 'DynamicImageSetRotation': Window %s is not a DynamicImage

Example

Placing text below an image only when the image has a texture, from ea_tomeofknowledge/source/tomewindow_bestiary.lua:

WindowClearAnchors( "BestiarySpeciesInfoText1" )
if( DynamicImageHasTexture( "BestiarySpeciesInfoImage" ) ) then
   WindowAddAnchor( "BestiarySpeciesInfoText1", "bottom", "BestiarySpeciesInfoImage", "top", 0, 10 )
else
   WindowAddAnchor( "BestiarySpeciesInfoText1", "top", "BestiarySpeciesInfoImage", "top", 0, 0 )
end
