Hi, I'm new to drools, and I made my first steps using the very nice video-tutorial "Build Pong in 13 minutes using JBoss Drools" found here: http://www.youtube.com/watch?v=Omj4PR3v-nI
Eclipse shows building errors, but Pong start anyway. What does this error mean? in move.drl there is following rule: *<rule "Move Bat Up" timer(expr: bat.speed, bat.speed) no-loop when* * ui : PongUI( ready == true )* * ( KeyPressed( keyText == "A" ) and bat : Bat( playerId == PlayerId.PlayerOne, y > pconf.padding + pconf.sideLineWidth )* * or* * KeyPressed( keyText == "K" ) and bat : Bat( playerId == PlayerId.PlayerTwo, y > pconf.padding + pconf.sideLineWidth ) ) * * td : TableDirty( ) * *then * * tableG = ui.getTablePanel().getTableG();* * tableG.setColor( Color.BLACK ); // background* * tableG.fillRect( bat.x, bat.y, bat.width, bat.height );* * * * modify( bat ) { y = bat.y - 2 };* * tableG.setColor( Color.WHITE ); // background* * tableG.fillRect( bat.x, bat.y, bat.width, bat.height ); * * modify( td ) { dirty = true };* *end* the error message is: [Error: unable to resolve method using strict-mode: org.drools.spi.KnowledgeHelper.td<http://org.drools.spi.knowledgehelper.td/> ()] [Near : {... @Modify with( td ) { dirty = true }; ....}] in another File (ui.drl) TableDirty is defined: *declare TableDirty* * @propertyReactive* * dirty : boolean* *end* Any ideas what this error message means? And why can I start pong despite this error? Thanks a lot for helping me Stefan
