Re: [Pharo-users] Woden - Rotate an Object from absolute referential

by merwanouddane＠gmail.com

Thanks for your answer ronnie, I did not manage to do it with node orientation, can you please be more specific ? De : Ronie Salgado EnvoyÃ© : âmardiâ â12â âmaiâ â2015 â09â:â44 Ã : Any question about pharo is welcome Hello Merwan, Currently is not possible because the only way to represent rotations is to use a matrix. I have to add support for quaternions, which gives me an opportunity to also add Euler angles. When I add support for Euler angles, you wil be able to do what you want easily. Currently, you have to use node orientation: (WDMatrix3 xrot: angle) to achieve what you are trying to do. Greetings, Ronie 2015-05-04 11:55 GMT-03:00 <merwanouddane(a)gmail.com>: Hello everyone, I am currently making a little demo with woden and I would like to rotate a cube, not from the relative referential but from the absolute one ( rotate X always rotate in the same direction even if I previously have rotated Y ). What currently happens is that when I rotate the cube, the referential rotates as well... Does anyone know how to counter this ? Thanks Merwan

Creating a Class in a Temporary Environment

by Sean P. DeNigris

I used to have creatingAClassInATemporaryNamespace | testingEnvironment morph | testingEnvironment := SystemDictionary new. ClassBuilder new name: #AClassForTesting inEnvironment: testingEnvironment subclassOf: Object type: Object typeOfClass instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'TemporaryTesting'. How do I do this with Slots? I tried: creatingAClassInATemporaryNamespace | testingEnvironment morph | testingEnvironment := SystemDictionary new. PharoClassInstaller make: [ :builder | builder superclass: Object; name: #AClassForTesting; environment: testingEnvironment; category: 'TemporaryTesting' ]. but got "key #SystemOrganization not found in SystemDictionary". ----- Cheers, Sean -- View this message in context: http://forum.world.st/Creating-a-Class-in-a-Temporary-Environment-tp4825963… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

I was just improving the existing hack (mainly because I want horizontal wheel events) until you guys finish something really good :) ----- Cheers, Sean -- View this message in context: http://forum.world.st/MouseWheel-events-tp4824839p4825958.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Sean We are working on SDL based events so we should probably synchronise. Because mouse wheel should be an event and not simulated. Merwan is producing touch event. Stef Le 11/5/15 02:34, Sean P.

If you've gotta have prorobuf then you've gotta have protobuf but there is a thrift implementation (https://thrift.apache.org/) and also a message pack implementation (https://code.google.com/p/stomp-serializer/) Benjamin Pollack-2 wrote > Hey all, > > Has anyone implemented protobufs for Pharo yet?
