DART scripting help

[Camera]

I was wondering what the code would be to hide certain textures based on gaining a target. For some reason I'm just hitting a mental block, right now I have:

ON LOAD:

this:RegisterEvent("Target_Selected")
this:RegisterEvent("Unit_Pet")

ON EVENT:

if Target_Selected("target") then
DART_Show(interface//ect...);
else
DART_Hide(interface//ect...);
end

If anyone could help it'd be greatly appreciated.

You can find a list of real events here: http://www.wowwiki.com/Events

DART's function need an id to a texture object, not a texture path/filename. DART_Hide(5) to hide texture #5 for instance. There's also the special variable ti which always holds the id of the texture which caused the script to run. Lastly capitalization is important.

OnLoad:
this:RegisterEvent("PLAYER_TARGET_CHANGED");

OnEvent:
if UnitName("target") then
DART_Show(ti);
else
DART_Hide(ti);
end

I'm still getting an error with the script, this is what I updated it to

On Load:
this:RegisterEvent("PLAYER_TARGET_CHANGED");

OnEvent:
if UnitName("target") then
DART_Show(6);
else
DART_Hide(6);
end

This should show / hide Texture 6 correct? The error I'm getting is:

[string "function DART_Texture6_Script_OnEvent(param, ti)..."]:2: `=' expected near `UnitName'


Not exactly sure what I'm doing wrong, haven't coded in a few years. Thanks for the help so far, if you could help me here I'd be very greatful.

If you're getting that error then that's not exactly what you have entered in OnEvent.

I copy / pasted, then I completely re-wrote it based off exactly what I put down, and the error went away. That's weird.


Thanks a lot Loz.

Is there a command for Target's target? I couldn't find it.
