dida55 Posted August 12, 2013 Share Posted August 12, 2013 Hey! So this mod should warp you to a location where you clicked on the map. It can be enabled/disabled, so you won't have to always use it, only when you want to travel fast, without getting exhausted. player:setX(x); player:setY(y);I am using the functions of IsoMovingObject, this should update the coordinates of the player, however, every time I click somewhere this error appears: http://f.cl.ly/items/0K0U031A382e0T1l2b1x/Image%202013.08.12%2022%3A44%3A04.pngI think the map has to be updated while you move and other things like that, but I cannot figure out how to do that Help is appreciated, thanks!

RoboMat Posted August 12, 2013 Share Posted August 12, 2013 I tried to do the same thing when I first started modding PZ and gave up after a few hours ^^ Link to comment Share on other sites More sharing options...
dida55 Posted August 12, 2013 Author Share Posted August 12, 2013 I tried to do the same thing when I first started modding PZ and gave up after a few hours ^^ Haha. Well, I've been reading the Javadocs and there are 4 functions I need to call somehow, I just don't know how:IsoChunk update()IsoChunkMap update()IsoCell update()IsoWorld update()If I knew how to call these, it may be fixed, but I can't figure it out from the Javadocs...

dida55 Posted August 12, 2013 Author Share Posted August 12, 2013 I have tried adding player:update(); zombie.iso.IsoCell:update(); zombie.iso.IsoChunk:update(); zombie.iso.IsoChunkMap:update(); zombie.iso.IsoWorld:update();but it did nothing change to the error screen. I hope someone can help :C Link to comment Share on other sites More sharing options...
RoboMat Posted August 13, 2013 Share Posted August 13, 2013 Packages in java work different than (tables) in lua. You can't simply call it with zombie.iso... I suggest that you look through all the getters in the Javadocs. There also is a list somewhere in the source (which I can't find now) which shows all global functions which can be simply called from lua. IIRC for example there should be a getCell() function. Maybe you could say:getCell():update() (I'm not sure though.) Link to comment Share on other sites More sharing options...

RoboMat Posted August 13, 2013 Share Posted August 13, 2013 Hm ... maybe you should look for a more simple mod to start with. I suggest that you read through the modding tutorials and also start looking at some Java and Lua coding guides (especially the Inheritence & OOP stuff). It's kind of hard to get a hang of modding if you don't know the basics about programming. Link to comment Share on other sites More sharing options...

It's kind of hard to get a hang of modding if you don't know the basics about programming. I do and completely understand how OOP works, just never actually used it.It's just that there are some basic things I'm missing out on and don't know how to use this Javadocs yet.Come on IRC!

dida55 Posted August 13, 2013 Author Share Posted August 13, 2013 I've spent 4 hours on digging the old forum and the javadocs and found out how to grab the world and the current cell, but still cannot figure out what that error means. Slightest help is welcome! Link to comment Share on other sites More sharing options...
RegularX Posted August 13, 2013 Share Posted August 13, 2013 You might look at some of the camping or rain barrel code. Lots of cell logic there. Link to comment Share on other sites More sharing options...

Will try to write a similar mod later. I need a way to warp through built doors which are bugged. Will post my results later. Link to comment Share on other sites More sharing options...
RoboMat Posted August 20, 2013 Share Posted August 20, 2013 Yes that's the one. Link to comment Share on other sites More sharing options...
WonkyLegs Posted August 20, 2013 Share Posted August 20, 2013 I've spent 4 hours on digging the old forum and the javadocs and found out how to grab the world and the current cell, but still cannot figure out what that error means. Slightest help is welcome!The error shows in which java method an error occured (the method on the top) and shows which other methods are affected by it. So you don't have to call all these update() functions. That's already done.If you start PZ via console.app you get the error message printed to your console. It shows another 2 rows then:Aug 20, 2013 2:15:22 PM zombie.gameStates.IngameState updateSEVERE: nulljava.lang.NullPointerException at zombie.iso.IsoChunk.update(IsoChunk.java:311) at zombie.iso.IsoChunkMap.update(IsoChunkMap.java:62) at zombie.iso.IsoCell.update(IsoCell.java:4803) at zombie.iso.IsoWorld.update(IsoWorld.java:1673) at zombie.gameStates.IngameState.update(IngameState.java:638) at zombie.gameStates.GameStateMachine.update(GameStateMachine.java:87) at zombie.GameWindow.logic(GameWindow.java:586) at zombie.GameWindow.run(GameWindow.java:980) at zombie.GameWindow.maina(GameWindow.java:856) at zombie.core.LaunchDialog.main(LaunchDialog.java:208)That means that an NullPointerException (basically a missing object/value) occured in zombie.iso.IsoChunk.update(), which is executed by zombie.iso.IsoChunkMap.update() and so on...I'm completely new to PZ modding, but I guess you have to set some other values on you current chunkMap to get the right chunk. I couldn't figure it out yet. Maybe analysing the spawn process of the player or zombies could help. Link to comment Share on other sites More sharing options...
