Construct Classic R2 SDK Download

Hello!

I'm looking to dive into the Construct Classic R2 SDK. Is it available for download anywhere?

Thanks,

Justin

The actual SDK is of version 0.99.3, compatible with R2, and you find it in the "Construct engineering" forum: http://www.scirra.com/forum/plugin-sdk-0993_topic37692.html

Hello Tulamide! Thank you very much for posting the link! Is there any documentation anywhere regarding how to code, compile, and apply custom behaviours (via the behaviours tab in the object properties panel)? I've searched via Google and around the forum but have found very little resources on how to code anything outside of using the events sheet.

I'm also interested in writing plugins but have found very little regarding documentation. I'm sure it's around somewhere but since the switch to Construct 2, it seems that some resources have become more difficult to find.

Or alternatively, where can I view the un-compiled Behaviour scripts?

ps - I'm working with Constructor Classic, not Construct 2

Thanks in advance!

The source for quite a few of the built in behaviors can be found on the Construct Classic SVN. Source for many of the plugins is also up there. In addition, here's a basic plugin tutorial from the old wiki.

It's recommended that you have a basic working knowledge of C++ to work with the SDK - not that I let that stop me. <img src="smileys/smiley17.gif" border="0" align="middle">

If you have any specific questions on how things work, go ahead and ask - there should still be a few people around here who can help you out, myself included.

Thanks linkman2004! I'm fairly new to C++ but come from a PHP, Javascript, AS3 background so I hope the learning curve won't be too painful.

Are behaviors written much differently than plugins? Are there any major changes I'd have to make while following that plugin tutorial for making my own behaviors instead?

I tried to compile the 8 Dir Movement and the Platform behaviors and it would appear that I need either MFC or ATL (which doesn't come with the Free Visual Studio Express). Is this true?

The difference is mostly in how they're setup - in "Main.h" there's a line near the top that starts with:

#define IDE_FLAGS

#define IDE_FLAGS OF_MOVEMENTPLUGIN

#define IDE_FLAGS OF_MOVEMENTPLUGIN | OF_NODRAW

pLink->info.x

this->info.x

Thanks linkman2004! I've started getting my hands dirty and have a few questions I thought I'd post out here.

Question 1: MFC Link Error

I followed the steps on that thread about getting the ATL and MFC requirements to work using VS 2008 Express. It's working great and I can compile the template and some of the behaviours. However, for one of the main behaviours I'm trying to disect (8 Dir Movement), I'm receiving the error:

LINK : fatal error LNK1104: cannot open file 'mfc42.lib'

Any thoughts on how to get this reference working?

Question 2: Referencing an external object from inside the behavior code

I'm attempting to write a series of behaviors for the different enemies I have in my game. For example, for some enemies, I'd like them to attack the player object if the player comes within 100px of them (very simple behavior. The 100px parameter will probably be something the designers sets in the Constructor interface). I'm curious how I can reference the player object from within the behavior C++ code that I've applied on my enemy sprite. There will always be only 1 player object (named "Player"). I'm familiar in the past using AS3 to do something such as "if(object is of class Player){ //then do something}" But I'm not sure where to start.

This is of course all very easy to script using the event sheet, however I don't want to have to copy this block of event sheet code onto all of my different layout "levels". And if I make a change to the behavior, I'd like to only make that change in 1 place and then it updates onto all the enemies in all of the levels where I have applied this behavior.

Thank you!

Whoops, sorry I missed this - let's see what I can do for ya.

Unfortunately I'm not sure I can answer your question about the link error - however, If I remember correctly, the 8 direction movement is working off a much older version of the SDK, and I believe some dependencies changed along the way, so that's probably the likely culprit.

As for question two, I actually needed something similar for my gravitation behavior. What I'd suggest is adding a static CRunObject* to your class declaration in Main.h after the ACE function declarations. In Runtime.cpp you'll have to define it - I have it after the #ifdef RUN_ONLY line.

Main.h:

////////////////////////////////////////////////////
// Data members

// Use when private variables (OF_PRIVATEVARIABLES) are enabled.
//vector<ExpStore> privateVars;

// Initialize the vector of object pointers for accessing data across objects
static CRunObject* playerObject;

//////////////////////////////////////////////////////////////////////////////////
// Runtime functions
//////////////////////////////////////////////////////////////////////////////////
#ifdef RUN_ONLY

CRunObject* ExtObject::playerObject;
