here is the link for the tutorial that i saw few days ago,http://www.jakel168.com/2010/09/how-to-make-mini-map-for-your-scene-in.html, its nice but seems not working on android platform.

this error is always popping out Assets/minmap.js(53,12):BCE0051: Operator ‘*’ cannot be used with a left hand side of type ‘float’ and a right hand side of type ‘Object’.

error at Assets/minimap.js at line: 48

pls :frowning: can anyone out there help me to make it work on android platform.

//just paste this code to the first/3rd person controller/you're character

Please format your code. It’s hard to read. Select the code and click the # icon in the post editor, or type the opening and closing CODE tags manually, for example:

[code]
... your code here ...
[/code]

Please provide the entire code file, unmodified, and point out exactly which line is producing the error.

sorry dude im new in this community and my English is not that good, my script is 100% running in PC standalone but when i switched to Android it’s not working anymore. btw thanks i already edited my post and point out the line where the error is

I’m not sure if the line-number matches up, but I noticed this:

function GetMapPos(pos : float, mapSize, sceneSize) {
return pos * mapSize/sceneSize;
}

You’re not declaring a type for mapSize and sceneSize. I’m not sure about Android, but on iOS you need to declare a type for all your variables - which would also include the properties from mapOffsetX to iconHalfSize.

Even if it’s not required, it’s a good idea to prevent errors and may make things more efficient.

dude i double checked the script and the error line should be on line 48 not 47 thanks, ill try to modify my codes when i get home and thank you for your suggestion, ill inform you immediately the result

hey dude thanks a lot, its now working i try to follow ur suggestion and now its 100% working on android platform here is the code

Sorry about the problem. The post was written exactly 2 years ago (what a coincidence!), haven’t had time to re-check it back.
I’ve since fixed the code to prevent any more problems for future readers. Thanks~!

Thank you also :slight_smile:
