  • Hi dude;

    Thanks for this amazing plugin, it's gave me solution I was looking for since the start of this month.

    I integrated you addon in my project, but I don't know why my construct 3 and project become buggy.

    And after few runtimes C3 freezs completely and I have to restart the Whole Browser.

    Also, I noticed that for some unknown reason, if 2 point are created at the same position, The Game+construct3+brwser (the whole fu**ing thing :) ) freezs completely.

    Do you have any solution plz

    Thanks again

    • Thank you.

      Can you open the console in your browser (F12) and get/copy the error message and post the message here? Then i can looking into it. Thx!

  • There is an issue with the use of angles... Once it is enabled once the spline finish, the sprite simply go invisible (Not the mode invisible) but if you look at the angle it is NaN in the debugger... I love this plugin want really want to use it in my project, but can't due to this issue ;(

  • Why did you remove this in debug panel?


    And you should use id="Rex_Spline" for c2 capx compatibility.

  • Great thanks for this.
