Some problems with hotspots...

[jav88]

Could you please tell me how to do the following things but not with script language because it's not so familiar for me....?
  I want to give a character an objetc, in order to make it possible to open a door which was locked before...(The door is a hotspot of the background)

You have to script, at least I had to.

OK, Then please tell me how I should use Scripy in that case...

[After]

In Room Editor>Areas select the hotspot and click on the "Interaction..." button.

Rt-click "Use inventory on hotspot" and choose "New action".

From the dropdown menu at the top of the dialog box that appears choose "Conditional - If inventory item was used", then use the "Change" button to set Value to be the item number. "OK".

Now there's a "Do Nothing" script under the Conditional.

Rt-click again, and choose what you want to do.
If nothing on the list is suitable, then (and only then)will you have to choose "Run script", which will show a blank page ready for scripting.
