ok, i figured out the problem with the plugin. It might have just been a stupid error (not selecting "use expression") but I now successfully am using it.

Still having the problem with building in release mode. The runtime portion of the plugin is still getting an error as mentioned below.

p.s. Are there any instructions on debugging a plugin at runtime?]]> Sat, 23 Apr 2011 17:44:17 +0000 http://www.scirra.com/forum/troubleshooting-expression-in-plugin_topic42546.html http://www.scirra.com/forum/troubleshooting-expression-in-plugin_topic42546_post264166.html#264166 Author: scidave

Think I might be narrowing down at least the runtime/release build error for GetInfo.

In internal.hpp the function is defined, but it has this config macro
// EDITTIME
#ifndef RUN_ONLY

And the function below is grayed out.

void WINAPI GetInfo(LPOINFO objectInfo)
{
objectInfo->MinimumVersion = MINIMUM_VERSION;
objectInfo->ideFlags = IDE_FLAGS;
}

Still not sure why it compiles fine under debug mode.

What does it mean in Visual Studio when there is a tiny little red circle with a minus sign sitting over the file name in the solution explorer? I'm using Visual Studio Pro 2010 and the project I coverted over was the MFC visual studio 2005 solution.]]> Sat, 23 Apr 2011 16:25:39 +0000 http://www.scirra.com/forum/troubleshooting-expression-in-plugin_topic42546.html http://www.scirra.com/forum/troubleshooting-expression-in-plugin_topic42546_post264154.html#264154 Author: scidave

Thanks Lucid for the details. Unfortunately, everything still looks ok. On a separate note, I am getting an error when building for release mode (something about:
ConstructSDK.def : error LNK2001: unresolved external symbol GetInfo
Release/ConstructSDK.lib : fatal error LNK1120: 1 unresolved externals

The whole debug/runtime/release mode settings for output and linker confuse the heck out of me. I still get a warning about output path being different than linker path even though they all seem to be the same. It compiles fine under the "Debug" build option.

I zipped up the relevant source files if you have time to take a look:

I'm at a loss at this point how to debug this. Is there a way to be able to debug the execution of this plugin?]]> Sat, 23 Apr 2011 13:01:03 +0000 http://www.scirra.com/forum/troubleshooting-expression-in-plugin_topic42546.html http://www.scirra.com/forum/troubleshooting-expression-in-plugin_topic42546_post264136.html#264136 Author: lucid

it might have something to do with ACETABLE.cpp, if you paste the code I can tell your for sure if it does, just the part relating to that expression. If it is the problem, you can probably figure out from this: the ADDEXP relating to the get color, check number 3 below, but here's a breakdown on the others as well, I don't remember if the tutorial went in detail:

[size=85:3scnhft6]
[code:3scnhft6]ADDEXP("My expression", "My category", "MyExpression", &ExtObject::eMyExpression, RETURN_INTEGER);[/code:3scnhft6][/size:3scnhft6]
[list=1:3scnhft6]
[*:3scnhft6]"My expression" should be what you see when in the Add Expression dialogue in the editor
[/*:m:3scnhft6]
[*:3scnhft6]"My category" is the category it's under
[/*:m:3scnhft6]
[*:3scnhft6]"MyExpression" is what you actually have to type to use the expression, like "Angle" is what is here in the sprite plugin's sprite.angle expression. not case-sensitive. Checking if this is an empty string is probably where I'd first look, or if it was invalid with a space or something that wouldn't work in construct.
[/*:m:3scnhft6]
[*:3scnhft6] &ExtObject::eMyExpression is a pointer to the c++ function that actually returns the value at runtime for this expression
[/*:m:3scnhft6]
[*:3scnhft6] RETURN_INTEGER is the return type of the c++ function. RETURN_STRING, or RETURN_FLOAT are two more valid constants, if you right-click - go to deceleration in visual studio on any one of these, you can see a full list.[/*:m:3scnhft6][/list:o:3scnhft6]

if it's not this, it's probably not to do with the ace_table, but I'd suggest checking number 3 before moving on to other troubleshooting]]> Sat, 23 Apr 2011 07:43:29 +0000 http://www.scirra.com/forum/troubleshooting-expression-in-plugin_topic42546.html http://www.scirra.com/forum/troubleshooting-expression-in-plugin_topic42546_post264128.html#264128 Author: scidave

I just built-up the example plugin to get started learning how to write these. Everything compiled fine and I was able to load the plugin with Construct.

Then I followed all the steps in the tutorial to build the color gradient plugin with the setcolors actions and getcolor expression. The problem is when I select "Get Color" from the expression box nothing happens and the window just closes. Any ideas on what I'm doing wrong? I can't find any mistakes in the code.]]> Sat, 23 Apr 2011 03:53:14 +0000 http://www.scirra.com/forum/troubleshooting-expression-in-plugin_topic42546.html
