Giving Goliath Base a weapon

I'm just a fish

Howdy. I'm working on a little modding project, fairly small to just sharpen my modding ability. I'll likely post the actual thread for the mod after this. Anyway, in this mod I'm making a million and one changes to the existing units in order to make them more useful on the battlefield. One of these changes I'd like to make is turning the Goliath into an incredibly useful multi-use combat unit. Anti-infantry support, anti-air and hopefully a heavier melee counter. With the latter, I was/am aiming to give the Goliath a strong melee attack he uses upon entering melee range since I've disabled his autocannons at that range. The attack is pretty much the Goliath kicking any poor Zergling or Zealot that tries to cop a feel in the face.

At first I thought it was as easy simply giving the Goliath Base a weapon, an attack code in it's Iscript and that'd be that. Buuuut I was horribly wrong. The Goliath does not use the weapon and so I figured if it were that easy someone would've done it before.

Here is my current iscript if it helps;

So my question at hand. Is it possible to give the Goliath Base a weapon? Or is it impossible/hardcoded otherwise?



None.

Changes: Removed "attackwith 1". Since you want the Goliath to attack with a melee weapon, attackmelee suffices.

Replace "attackmelee 1" with "attackmelee x" where x is the weapon ID (weapons.dat) of a more appropriate weapon (e.g. "z" where z is the weapon ID of the Zergling -- I don't have actual IDs but you can look them up with DatEdit or whatever). Look up other melee weapon IDs and their properties for an idea as to what is common in between melee weapons. (I don't have any tool access so this is the best help I can provide.)

You can replace 894 with some other sound ID that might be more fitting.

You should use the opcode that has to do with detecting if the target is within a certain range before jumping to another block that has the actual attack to be used.

This may be of interest: http://www.staredit.net/topic/15308/ Scroll down to my third post where the download link is and feel free to open up the EXE of the mod and browse it with an MPQ viewer. If I recall correctly, I left original script code in their for various units.

Of particular interest should be the Goliath, wherein I modified it to have 4 weapons, each of which are fired at different intervals of distance with separate cooldowns and target flags, which appears to be the effect for which you are aiming. Feel free to go through it and use it to your advantage.

Ah! Thank you very much, that worked wonders :). Got the goliath to do exactly what I'd like albeit with a few "bugs". It's melee weapon replaces the turret's "1" weapon in the select/command bar thing. Is there a way I can hide it in-game somehow? The goliath also attacks air units with the melee attack despite not have the air target flag checked or air attack codes in the Iscript. Here is the current code;

Try setting any air attack-relevant animations to the Goliath_Base_GndAttkToIdle block.

Not sure what you mean by the command bar thing. Do you mean where it displays the weapon and armour icons? That status bar can only display up to 4 or 5 icons I think, so you'll probably have to prevent the Goliath's armour icon from appearing.

Aye yeah, the in-game armor and weapon icons. How would I go about modifying that? If anything, I'd just like to hide the melee weapon icon.

I altered the code to have the AirAttack relevant bits to use GndAttkToIdle however they kept reverting to AirAttkToIdle whenever I saved. So I made a dummy AirAttkInit that went to GndAttkToIdle which worked. The Goliath no longer attacks air units with the melee weapon. All that is left is the icon. Thank you kindly for your help so far :).

With respect to the GndAttkToIdle thing: I meant something like this in the headers:
Code
GndAttkInit       Goliath_Base_GndAttkInit
AirAttkInit       Goliath_Base_GndAttkToIdle
...
GndAttkToIdle     Goliath_Base_GndAttkToIdle
AirAttkToIdle     Goliath_Base_GndAttkToIdle

but it sounds like you got it on your own.

I don't remember the exact fields that you need to check in order to prevent certain icons from appearing. Look at the armour data entry for buildings and compare the upgrades.dat and stuff with a normal unit. (Since buildings normally don't have an armour icon, you can try looking for it as a difference between it and normal armours and weapons.)

You're welcome~ :3
