e. No endorsement. Nothing in the NTOS License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Software is, connected with, or sponsored, endorsed, or granted official status by, the Author or others designated to receive attribution as provided in Section III(1)(a)(A)(i).
2. Other rights.
a. Moral rights, such as the right of integrity, are not licensed under the NTOS License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Author waives and/or agrees not to assert any such rights held by the Author to the limited extent necessary to allow You to exercise the Licenced Rights, but not otherwise.
b. Patent and trademark rights are not licensed under the NTOS License.
c. To the extent possible, the Author waives any right to collect royalties from You for the exercise of the Licenced Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme.

Section III. License Conditions.
Your exercise of the Licensed Rights is expressly made subject to the following conditions.

1. Attribution.
a. If You Distribute the Software (including in modified, or based form), You must:
A. retain the following if it is supplied by the Author with the Software:
i. identification of the creator(s) of the Software and any others designated to receive attribution, in any reasonable manner requested by the Author (including by pseudonym if designated);
ii. a copyright notice;
iii. a notice that refers to the NTOS License;
iv. a notice that refers to the disclaimer of warranties;
v. a URI or hyperlink to the Software to the extent reasonably practicable;
indicate if You modified the Software and retain an indication of any previous modifications; and
indicate the Software is licensed under the NTOS License, and include the text of, or the URI or hyperlink to, the NTOS License.
b. You may satisfy the conditions in Section III(1)(a) in any reasonable manner based on the medium, means, and context in which You Distribute the Software. For example, it may be reasonable to satisfy the conditions by providing a URI or hyperlink to a resource that includes the required information.
c. If requested by the Author, You must remove any of the information required by Section III(1)(a)(A) to the extent reasonably practicable.

2. Distribute ALike
In addition to the conditions in Section III(1), if You Distribute the Modification You produce, the following conditions also apply.
A. The Modification Author's License You apply must be the NTOS License
B. You must include the text of, or the URI or hyperlink to, the Modification's Author's License You apply. You may satisfy this condition in any reasonable manner based on the medium, means, and context in which You Distribute the Modification.
C. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Modification that restrict exercise of the rights granted under the Modification's Author's License You apply.
D. You may not apply any fee to access the Modification

3. Distribution of code
In addition to the conditions in Section III(1), if You Distribute a Based Software, the following conditions also apply:
A. You must include the text of, or the URI or hyperlink to, refering to this License. You may satisfy this condition in any reasonable manner based on the medium, means, and context in which You Distribute the Based Software.
B. You must also include Section III(1)(a)(A)(ii-v) in the the Based Software Code.

Section IV. Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Software:

for the avoidance of doubt, Section II(1)(a) grants You the right to extract, reuse, reproduce, and Dstribute all or a substantial portion of the contents of the database for NonCommercial purposes only;
if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is the Modification, including for purposes of Section III(2); and
You must comply with the conditions in Section III(1) if You Distribute all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section IV supplements and does not replace Your obligations under the NTOS License where the Licensed Rights include other Copyright and Similar Rights.


Section V – Disclaimer of Warranties and Limitation of Liability.

1. Unless otherwise separately undertaken by the Author, to the extent possible, the Author offers the Software as-is and as-available, and makes no representations or warranties of any kind concerning the Software, whether express, implied, statutory, or other. This includes, without limitation, warranties of title, merchantability, fitness for a particular purpose, non-infringement, absence of latent or other defects, accuracy, or the presence or absence of errors, whether or not known or discoverable. Where disclaimers of warranties are not allowed in full or in part, this disclaimer may not apply to You.
2. To the extent possible, in no event will the Author be liable to You on any legal theory (including, without limitation, negligence) or otherwise for any direct, special, indirect, incidental, consequential, punitive, exemplary, or other losses, costs, expenses, or damages arising out of the NTOS License or use of the Software, even if the Author has been advised of the possibility of such losses, costs, expenses, or damages. Where a limitation of liability is not allowed in full or in part, this limitation may not apply to You.

3. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.


Section VI – Term and Termination.

The NTOS License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with the NTOS License, then Your rights under the NTOS License terminate automatically.

Where Your right to use the Software has terminated under Section 6(a), it reinstates:
automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or
upon express reinstatement by the Author.
For the avoidance of doubt, this Section 6(b) does not affect any right the Author may have to seek remedies for Your violations of the NTOS License.
For the avoidance of doubt, the Author may also offer the Software under separate terms or conditions or stop distributing the Software at any time; however, doing so will not terminate the NTOS License.
Sections I, V, VI, VII, and VI survive termination of the NTOS License.

Section VII – Other Terms and Conditions.

The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed.
Any arrangements, understandings, or agreements regarding the Software not stated herein are separate from and independent of the terms and conditions of the NTOS License.

Section VIII – Interpretation.

For the avoidance of doubt, the NTOS License does not, and shall not be interpreted to, reduce, limit, restrict, or impose conditions on any use of the Software that could lawfully be made without permission under the NTOS License.
To the extent possible, if any provision of the NTOS License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from the NTOS License without affecting the enforceability of the remaining terms and conditions.
No term or condition of the NTOS License will be waived and no failure to comply consented to unless expressly agreed to by the Author.
Nothing in the NTOS License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Author or You, including from the legal processes of any jurisdiction or authority.

In case of a specific issue not specified in the NTOSL, Berne Convention for the Protection of Literary and Artistic Works, which reserves all rights to the Author applies. You can find Berne Convention for the Protection of Literary and Artistic Works at http://www.wipo.int/treaties/en/text.jsp?file_id=283698.

<h1><img src="https://github.com/Ad5001/PlayerSelectors/raw/master/icon.png">&nbsp;&nbsp;PlayerSelectors</h1>
Implementation of minecraft selectors into PocketMine!

<h1><img src="https://png.icons8.com/?id=365&size=1x">&nbsp;&nbsp;How to install?</h1>
1. Download the .phar file from the link given at the top of the repo
2. Put that phar into your "plugins" folder
3. Restart your server and Selectors should be reay to go!

<h1><img src="https://png.icons8.com/?id=3330&size=1x">&nbsp;&nbsp;Implemented features</h1>
PlayerSelectors implements all the default minecraft selectors:<br>
- @a - All players<br>
- @p - Nearset player<br>
- @e - Entities<br>
- @r - Random player<br>
- @s - Self/Sender<br>
but also features a custom made one:<br>
Since PocketMine implements a multi world system, you can easily select players from your current world using the "@w" selector!
<br><br>
Minecraft also supports specific search parameters such as the distance from the sender, the count of matched player/entities, ...<br>
All the standard minecraft search params can be used with the syntax

```
@<selector name>[key=param,other=value]
```

EXEPT the team & score params since the /scoreboard command isn't implemeted into pocketmine yet<br> Thought, one new params comes with this plugin: the "lvl" param which is for searching in a specific level.

Have fun!
