//--------------------------------------------------------------------------
*full trigger at the bottom*
I have problems with arrays within struct arrays; somehow I override data in one array, when cleaning up another...
I'm working on a FF like battle zone and want store all creep data of an "enemy wave" in an struct, which itself is an struct array.
I want to spawn up to 5 units, store them in an struct array "EnemyWaves[]" of struct "EnemyData". Within that struct I have several arrays that
keep track of all the data for every unit within that wave.
So, I want to spawn the first wave: EnemyWaves[0], that contains 1 unit of type A; after that wave, I want to remove that wave EnemyWaves[0] and spawn the next wave EnemyWaves[1], which contains 1 unit of Type A and 2 units of Type B; ...
Now the problem is: when setting up or removing a wave, somehow the data gets overriden, and I have no idea what I'm doing wrong.
Through testing I always get down to these functions: "SetupWave", "SpawnNextWave" and the method ".reset"; but I can't figure it out.
This is the enemy setup that I'm calling
So it should come up:
First wave, 1 unit of type c001
Second wave, 1 unit of type c000, 2 units of type c001, 5 units max (there will be only 3 though)
Third wave, 5 units of type c001
Fourth wave, 1 unit of type c000
But what happens is:
First wave, 1 unit of type c001 (works)
Second wave, 2 units of type c001 (doesn't work); the first unit ".creepTypeId[0]" gets overriden/set to 0 in the ".reset" call of the PREVIOUS wave! so a unit is spawned of UnitType "0"
Now I leave out the ".reset" call and this happens:
First wave, works
Second wave, works
Third wave, doesn't work; instead of 5 units of type c001 there are 4 of c001 and 1 of c000
Fourth wave, works
Another weird thing (picture below):
-The picture on the left shows the unitType for every unit; the units slot within its wave; and the wave itself => this is all correct
-Now in the center picture there is the output of all the creepTypeIds of the second wave (EnemyWaves[1]); in the green box are the 3 units that will be spawned (which is correct), the "0" underneath would be the fourth unit (but I only set up 3 units; so this is correct, too). But the number underneath, the fifth unit, should be 0 as well! But it isn't. And I've never set it up. And I couldn't figure out where it does get setup.
-The picture on the right shows again the creepTypeId of the second wave; I gave out the creepId before the ".reset" call of the previous wave, and after. After the previous wave(&unit) gets destroyed, the first unit of the second wave gets also reset!
