I’m doing app for social network. and my app started in iframe window.
Source page pass parameter to that window like user_id, session and another parameters something like
.../my_game.html?user_id=XXXX&session_id=XXXXX
And I’m intersting how can i read that parameters in the game.
thanks.
parse in js and pass in extra_params ?
and how to get them in defold ?
You can pass config key-value pairs and read them with sys.get_config(). See:
and
sims like i’m doing something wrong.
in index.html template I added following lines
var extra_params = {
archive_location_filter: function( path ) {
return ("{{DEFOLD_ARCHIVE_LOCATION_PREFIX}}" + path + "{{DEFOLD_ARCHIVE_LOCATION_SUFFIX}}");
},
{{#HAS_DEFOLD_ENGINE_ARGUMENTS}}
engine_arguments: ["{{DEFOLD_ENGINE_ARGUMENTS}} --config=test_param=111333"],
{{/HAS_DEFOLD_ENGINE_ARGUMENTS}}
splash_image: "{{DEFOLD_SPLASH_IMAGE}}",
custom_heap_size: {{DEFOLD_HEAP_SIZE}}
}–config=test_param=111333
and then in the script trying to get this value
print(sys.get_config("test_param"))
but result is nil
thanks i solved the issue.
So here is how to do that
1 In game.project defined new section and variable (not sure if it’s mandatory or not). (upd: Add this only if you need default value)
[test]
value = 5555555
2 In index.html template instead of one string parameter you need to make an array with string parameters
that’s it.
thanks again!
upd. this is the whole section which i use
<script type='text/javascript'>
var engine_args = []
{{#HAS_DEFOLD_ENGINE_ARGUMENTS}}
engine_args.push("{{DEFOLD_ENGINE_ARGUMENTS}}")
{{/HAS_DEFOLD_ENGINE_ARGUMENTS}}
var url_params = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for(var i = 0; i < url_params.length; i++)
{
var new_arg = "--config=url.".concat(url_params[i])
engine_args.push(new_arg);
}
var extra_params = {
archive_location_filter: function( path ) {
return ("{{DEFOLD_ARCHIVE_LOCATION_PREFIX}}" + path + "{{DEFOLD_ARCHIVE_LOCATION_SUFFIX}}");
},
engine_arguments: engine_args,
splash_image: "{{DEFOLD_SPLASH_IMAGE}}",
custom_heap_size: {{DEFOLD_HEAP_SIZE}}
}
Module.runApp("canvas", extra_params);
/* Fullscreen button */
document.getElementById("fullscreen").onclick = function (e) {
Module.toggleFullscreen();
};
</script>and then in lua you can use
sys.get_config("url.your_param_here")
Cool. You don’t need to add anything to the game.project settings btw.
