Summary

0006562: XEngine is confused about types of constants in llAttachToAvatarTemp

Description

It looks like XEngine has some mismatch regarding the types of some LSL constants for llAttachToAvatarTemp. This doesn't happen for llAttachToAvatar.

Steps To Reproduce

Place this script on a cube, and touch the cube. You'll get a runtime error.

integer i = 0;

default
{
    state_entry()
    {
        llSay(0, "Script running");
    }

    touch_start(integer n)
    {
        if (i == 0)
        {
            i++;
            llRequestPermissions(llDetectedKey(0), PERMISSION_ATTACH);
        }
        else
            llDie();
    }

    run_time_permissions( integer vBitPermissions )
    {
        if( vBitPermissions & PERMISSION_ATTACH )
        {
            llAttachToAvatarTemp( ATTACH_LHAND );
        }
        else
        {
            llOwnerSay( "Permission to attach denied" );
        }
    }
}

Notes
(0027143) greg0254 (reporter) 2014-12-28 00:07	This is still an issue with r/25604 commit f3ab7c0f5c76. The message it produces is: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> OpenSim.Region.ScriptEngine.Shared.ScriptException: MOD Runtime Error: llAttachToAvatarTemp: parameter type mismatch; expecting Int32, type(parm)=System.Int32 A workaround is to add a redundant cast to the parameter, e.g. llAttachToAvatarTemp( (integer)ATTACH_LHAND ); (I'm also curious as to why it's necessary to enable MOD functions for temp attachments to work, if anyone cares to explain this.)
