Hey everyone! So I've been working on a game called Secret of Escape, an action stealth game where you only have a short time to make it through each level. You can check out a gameplay trailer I made for it here:

I've been working on it for a year, but I've been having performance issues lately. I'd like the game to run on laptops as well as gaming desktops, but some of the gameplay levels perform really slow when the game runs fine in menus while using a laptop with a 2GHz CPU.

So I'm looking for anyone with experience with Construct2 to review my project/code so far, and see where it can be improved. Contact via PM with more info.

I've fixed it, according to the github repo for Node-Webkit, there is a certain compatibility issues with WebGL and Node-Webkit. Basically has to do with DirectX 9, those files are dependent for some reason.

I installed DX9 on my Windows 8.1 machine and now the game runs full speed!

I have a strange issue with my laptop. I'm using this basic physics project for my example test: https://dl.dropboxusercontent.com/u/30381754/Physics%20Test.capx

My desktop PC is a Windows 7 64-bit machine with Intel Core i5 2500K CPU and AMD HD Radeon 7800 Graphics card. The physics example (and a game I'm currently working on) runs fine with no performance drops and in Node-Webkit/Chrome/Firefox uses the WebGL Renderer.

My laptop is a Windows 8.1 64-bit machine with Intel Core i5-4200U CPU and integrated graphics. The physics example has a slightly choppy framerate and while it uses the WebGL Renderer in Chrome and Firefox, it uses the Canvas2D renderer in Node-Webkit.

I've tried updating the graphics driver and OpenGL appears to work fine for other applications, could this be an issue with the Node-Webkit libraries?

Doubt anyone is reading this but back in December I did a write up which included a way of implementing the Sprite Lamp generated normals into Construct2.

I have the same problem occurring on both my Windows 7 (64-Bit) Desktop and my Windows 8.1 (64-Bit) Laptop. It effects all three web browsers specified.

EDIT: It also effects Node-Webkit on my desktop.

Just reinstalled Google Chrome and now everything works including the WebGL effects. I think something screwed up my Chrome install.

Weird, I have the latest driver version of my graphics card (AMD HD Radeon 7800 series) and this issue only occurs in Google Chrome (the effects appear fine in IE11 and Node-Webkit). Could there be something up with how my graphics driver handles Chrome? Or Chrome's WebGL renderer?

I've had a mess around with other effects. Certain distortion effects like Water Ripple and Pulse cause the image to be partially drawn instead of being fully visible.

Steps to reproduce:

1. Add any sprite to the project

2. Add any blur effect to the sprite (I've tried this with Horizontal Blur, Vertical Blur and Radial Blur)

3. Preview

Observed result:

Sprite is not visible.

Expected result:

A sprite should be visible, but with the added blur effect as previewed in the game editor.

Browsers affected:

Chrome: yes

Firefox: unknown

Internet Explorer: no (tested with IE11

Operating system & service pack: Windows 7 SP1

Construct 2 version: r152

One other option I found is to replace the none package files with a newer version of Node-Webkit. Just tested the game using this method and no slowdowns whatsoever!

While I've been using Construct2 with Node-Webkit for a while, I've recently noticed an issue with the exported application for one of my projects.

I use R0J0Hound's Canvas Plugin along with his Shadow Casting method. When I run the project in Google Chrome, it runs perfectly fine, however when I run it as a Node-Webkit application, there is a very noticeable lag.

One supposed reason is that Node-Webkit recently changed their rendering library.

Therefore I'm looking at other ways to export a HTML5 Construct2 game as a Desktop Application. Anyone have any good recommendations?

This is strange, but when I try this shadow caster (and my game which uses your shadow casting technique) on Google Chrome it runs very smoothly. But when I run it on Node-Webkit, both run very slow and laggy.
