如果你使用HGE開發(fā)游戲，那就要注意了。
下面是它的license說明
| BASS is free for non-commercial use. If you are a
non-commercial entity (eg. an individual) and you are not charging for
your product, and the product has no other commercial purpose, then you
can use BASS in it for free. Otherwise, you will require one of the
following licences. |
 |
Shareware
licence: €100
The "shareware" licence allows the usage of
BASS in an unlimited number of your shareware products, which must sell
for no more than 40 Euros each. If you're an individual (not a
corporation) making and selling your own software (and its price is
within the limit), this is the licence for you. |
 |
Single
Commercial licence: €950
The "single commercial" licence
allows the usage of BASS in a single commercial product. |
|
Unlimited
Commercial licence: €2450
The "unlimited commercial" licence
allows the usage of BASS in an unlimited number of your commercial
products. This licence applies to a single site/location. |
| note
that all prices are quoted in Euros, but payment can also be made in
several other currencies |
| These licences are on a per-platform basis.
There is a 20% reduction when purchasing a licence for both platforms,
eg. the Shareware licences are €160 instead of €200. |
| In all cases there are no royalties to pay and
you can use future BASS updates without further cost.
Reselling/sublicensing is not permitted. Your products must be end-user
products, eg. not components used by other products. Please note that
these licences only cover your own software, not the publishing of
other's software. If you have got any questions, please get in
touch. |
