ThaT helped! I set the translation to the par 2 4 6 and it is now in the right place relative to the world. Only issue now, is that it will start at the right place. But the line will continue on forever. Do I need to do anything more with the tessalator?

Bump!

Thanks for the link to the minecraft code, i was looking for that! I now have a line! Although it appears to render relative to the player now.. here is my amended code. List<Position> laserToList = ent.laserToList; if (laserToList != null && laserToList.size() > 1) { // System.out.println("LOL"); for (int i = 0; i < laserToList.size() - 1; i++) { // System.out.println(laserToList.get(i).toString()); // System.out.println(laserToList.get(i + 1).toString()); double doubleX = ent.xCoord; double doubleY = ent.yCoord; double doubleZ = ent.zCoord; GL11.glPushMatrix(); GL11.glEnable(GL11.GL_BLEND); GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA); GL11.glTranslated(0, 0, 0); GL11.glColor3ub((byte)255,(byte)0,(byte)0); GL11.glLineWidth(10.0F); float mx1 = ent.xCoord - (float) laserToList.get(i + 1).x; float my1 = ent.yCoord - (float) laserToList.get(i + 1).y; float mz1 = ent.zCoord - (float) laserToList.get(i + 1).z; float mx2 = ent.xCoord - (float) laserToList.get(i + 1).x; float my2 = ent.yCoord - (float) laserToList.get(i + 1).y; float mz2 = ent.xCoord - (float) laserToList.get(i + 1).z; Tessellator tessellator = Tessellator.instance; tessellator.startDrawing(3); tessellator.addVertex(mx1, my1, mz1); tessellator.addVertex(mx2,my2, mz2); tessellator.draw(); GL11.glEnable(GL11.GL_TEXTURE_2D); GL11.glDisable(GL11.GL_BLEND); GL11.glPopMatrix(); } } else { // System.out.println(laserToList.size()); } I am now changing the coordinates for the laser origin and end points so that they are relative to the TE as you suggested: TE position - laser origin position

So, I'm trying to render a series of lines to represent lasers. I am sending a packet from server to client that will add a series of coords into a list on my tile-entity. I am then picking this list up from my Tile-Entity renderer and trying to display lines from point to point; please see the code below. List<Position> laserToList = ent.laserToList; if (laserToList != null && laserToList.size() > 1) { // System.out.println("LOL"); for (int i = 0; i < laserToList.size() - 1; i++) { System.out.println(laserToList.get(i).toString()); System.out.println(laserToList.get(i + 1).toString()); double doubleX = Minecraft.getMinecraft().thePlayer.posX - 0.5; double doubleY = Minecraft.getMinecraft().thePlayer.posY + 0.1; double doubleZ = Minecraft.getMinecraft().thePlayer.posZ - 0.5; GL11.glPushMatrix(); GL11.glTranslated(-doubleX, -doubleY, -doubleZ); GL11.glColor3ub((byte)255,(byte)0,(byte)0); float mx1 = (float) laserToList.get(i + 1).x; float my1 = (float) laserToList.get(i + 1).y; float mz1 = (float) laserToList.get(i + 1).z; float mx2 = (float) laserToList.get(i + 1).x; float my2 = (float) laserToList.get(i + 1).y; float mz2 = (float) laserToList.get(i + 1).z; GL11.glBegin(GL11.GL_LINES); GL11.glVertex3f(mx1, my1, mz1); GL11.glVertex3f(mx2, my2, mz2); GL11.glEnd(); GL11.glPopMatrix(); } } else { // System.out.println(laserToList.size()); } This code is definitely getting hit, as you can see in my client console output: 2014-01-16 19:15:41 [iNFO] [sTDOUT] {150.0, 64.0, 273.0} 2014-01-16 19:15:41 [iNFO] [sTDOUT] {150.0, 64.0, 270.0} The issue is, i am not seeing my lines at all! What am i doing wrong!

Well now I feel dumb! Thanks for your help in clearing this one up

So you know where the problem lies with the entity? I was originally going to use a tileentity for this, but then i also want it to go through transparent surfaces, e.g glass.. so an entity seemed like a better solution. If i cant get it to work ill go back to a tileentity and just make it only go through air.

I know for sure that this is called, as I can insert a println in there and it will output to the console

Thanks for the reply, I seem to be doing similar things, but im not trying to spawn a mob so its slightly different. My code can be found here if you want a more detailed look: https://github.com/lexwebb/opticraft/

Updated the part which actually initiates the Entity: for(int i = this.yCoord; i <= linkedDetector.y - 1; i++){ if (!worldObj.isRemote){ EntityBeam entity = new EntityBeam(worldObj, "UD"); entity.setPosition(xCoord, yCoord + i, zCoord); worldObj.spawnEntityInWorld(entity); //worldObj.playSoundEffect((double)xCoord + 0.5D, (double)yCoord + 0.5D, (double)zCoord + 0.5D, "random.fizz", 0.1F, worldObj.rand.nextFloat() * 0.1F + 0.9F); } } It appears from my debug line the renderer is never getting called. But it is getting initiated... No one got any idea?

Have a look at TileEntityFurnace ISidedInventory code, its quite useful

Bump, Anyone?

Thanks TTG! it was shouldUseRenderHelper(INVENTORY_BLOCK) returns true that i needed. Here is a screenshot of everything working nicely! thanks both of you for you help

Wahey! It displays everywhere but the inventory!, where I just get an invisible item. My code for that part is below, see any issues? } else if(type == ItemRenderType.INVENTORY){ RenderBlocks blockRenderer = (RenderBlocks)data[0]; //Entity entity = (Entity)data[1]; // entity holding the item GL11.glPushMatrix(); Minecraft.getMinecraft().renderEngine.bindTexture(new ResourceLocation(ModInfo.ID.toLowerCase() + ":textures/items/LaserWrench.png")); float scale = 0.7F; GL11.glScalef(scale, scale, scale); GL11.glRotatef(180, 1, 0, 0); // Forward-Backwards Up-Down model.render(null, 0.0F, 0.0F, 0.0F, 0.0F, 0.0F, 0.0625F); GL11.glPopMatrix(); }

Thanks for all the help guys, I realised that the way I was doing the ID's was ignoring Minecraft adding 255 to the ID, I just added 255 into the register item render code and it solved it. My rendering was all messed up, so thanks for help fixing that red!

Yeah its alled along with those other renderers, which do register. The Both the item and that use the Ids.LaserRench constant

Having added some debug code, it appears that renderItem in the renderer is never getting called. Which is weird, as my code is pretty darn similar in every other aspect.

That's the code i adapted for this. Does the vanilla item need a texture? Also i cannot see it in 3rd person

The texture shouldn't matter as its just place holder code, this is meant to be a custom modelled 3D item

I am trying to make a custom rendered tool that will show its model in first and third person. However at the moment it is only showing a blank texture.

Well now i just feel stupid! Thanks!

Thanks! I have fixed the not being able to click items by adding missing code to getServerGuiElement to return my Container (Updated on GitHub). However, now when I try and access the inventory the windows instantly closes. Any ideas?

I have made a custom TileEntity that has a single slot inventory. However, when I try to click an item in the created inventory, it just drops the item. It seems like a client/server desync, but I'm not sure. Also, when i shift click i get this error spammed to my console: 2013-11-21 20:30:25 [iNFO] [sTDOUT] at net.minecraft.inventory.Container.retrySlotClick(Container.java:520) 2013-11-21 20:30:25 [iNFO] [sTDOUT] at net.minecraft.inventory.Container.slotClick(Container.java:291) It repeats so much that i cannot view the actual error, which is very useful... My code can be found here: https://github.com/lexwebb/opticraft TileEntity: https://github.com/lexwebb/opticraft/blob/master/entitys/TileEntityItemLaser.java Block: https://github.com/lexwebb/opticraft/blob/master/blocks/ItemLaserBlock.java Container: https://github.com/lexwebb/opticraft/blob/master/blocks/containers/ItemLaserContainer.java GuiHandler: https://github.com/lexwebb/opticraft/blob/master/client/gui/GuiHandler.java If there's anything I missed please let me know! Thanks in advance!

Thanks, having come from Bukkit modding im used ot doing it that way

No matter what i try i cannot seem to get my TileEntity to read its NBT data on create. Saving works fine though. The 'Code' button does not work for me so here's a paste of my code: http://puu.sh/5hjt0.txt
