william already posted a tutorial on how to do this in my screenshot/video topic, but I'll make a new tutorial topic so it'll be easier for people to find it.
First, goto the Interface folder, then PriorityPanel. In there, you'll see two .bmp's, Priorities.bmp and Priorities_old.bmp. Rename Priorities.bmp to something else, like Priorities_orig, then rename Priorities_old to Priorities.
Now open the cfg and search for PriorityImages
You'll see this.
PriorityImages {
; languages
;<PriorityType> <PriorityNameInGame>:<NormalImage>:<PressedImage>
AI_Priority_Train Train_Rock_Raider:Interface\Menus\TrainAs.bmp:Interface\Menus\PTrainAs.bmp:Interface\Menus\NTrainAs.bmp
AI_Priority_GetIn Use_Vehicle|PriSFX_Drive:Interface\Menus\enter.bmp:Interface\Menus\Penter.bmp:Interface\Menus\Nenter.bmp
AI_Priority_Crystal Collect_Energy_Crystals|PriSFX_Crystals:Interface\Priorities\collectCrystal.bmp:Interface\Priorities\PcollectCrystal.bmp:Interface\Priorities\NcollectCrystal.bmp
AI_Priority_Ore Collect_Ore|PriSFX_Ore:Interface\Priorities\collectOre.bmp:Interface\Priorities\PcollectOre.bmp:Interface\Priorities\NcollectOre.bmp
AI_Priority_Repair Building_Repairs|PriSFX_Repair:Interface\Menus\repair.bmp:Interface\Menus\Prepair.bmp:Interface\Menus\Nrepair.bmp
AI_Priority_Clearing Clear_Rubble:Interface\Menus\ClearRubble.bmp:Interface\Menus\PClearRubble.bmp:Interface\Menus\NClearRubble.bmp
AI_Priority_Destruction Drilling|PriSFX_Drilling:Interface\Priorities\deconstruct.bmp:Interface\Priorities\Pdeconstruct.bmp:Interface\Priorities\Ndeconstruct.bmp
AI_Priority_Construction Construction|PriSFX_Construction:Interface\Menus\building.bmp:Interface\Menus\Pbuilding.bmp:Interface\Menus\Nbuilding.bmp
AI_Priority_Reinforce Reinforce_Walls|PriSFX_Reinforce:Interface\Menus\Reinforce.bmp:Interface\Menus\PReinforce.bmp:Interface\Menus\NReinforce.bmp
AI_Priority_Recharge Recharge_Energy_Crystals|PriSFX_Recharge:Interface\Menus\Recharge.bmp:Interface\Menus\PRecharge.bmp:Interface\Menus\NRecharge.bmp
}
Now you can add in three new priorities to the list (you can add more if you want, but you'll need a new Priorities.bmp with more slots and you'll also have to add new PrioritiesImagePositions))
For this tutorial I'll be using AttackRockMonster, BuildPath and Upgrade (full list of priorities at the bottom of this post)
Paste this under AI_Priority_Recharge (you can change this to whatever you want)
AI_Priority_AttackRockMonster Defend_Rock_Raiders_HQ:Interface\Menus\get_Gun.bmp:Interface\Menus\Pget_Gun.bmp:Interface\Menus\Nget_Gun.bmp
AI_Priority_BuildPath Build_Power_Path:Interface\Menus\buildpath.bmp:Interface\Menus\Pbuildpath.bmp:Interface\Menus\Nbuildpath.bmp
AI_Priority_Upgrade Upgrade:Interface\Menus\Upgrade.bmp:Interface\Menus\PUpgrade.bmp:Interface\Menus\NUpgrade.bmp
Now, go over to Levels {.
Go to Tutorial01 and find Priorities {.
Under AI_Priorities_Recharge TRUE, add this
AI_AttackRockMonster TRUE
AI_BuildPath TRUE
AI_Upgrade TRUE
Now you'll just have to add this to every single mission and tutorial... hehe.
And you're done!
You can also add your own Priority sounds, but I'm too lazy to make a tutorial for that...
