In the stock scripts, they have an if/else if statement for every possible combination for powerups, how would I make it so it detects how many powerup shaders are active, and adjust accordingly?

This code in the function "powerup_hud_overlay" handles the posititioning of the hud:

Code Snippet

Plaintext

for(i = 0; i < 2; i++)
	{
		level.powerup_hud[i] = create_simple_hud();
		level.powerup_hud[i].foreground = true; 
		level.powerup_hud[i].sort = 2; 
		level.powerup_hud[i].hidewheninmenu = false; 
		level.powerup_hud[i].alignX = "center"; 
		level.powerup_hud[i].alignY = "bottom";
		level.powerup_hud[i].horzAlign = "center"; 
		level.powerup_hud[i].vertAlign = "bottom";
		level.powerup_hud[i].x = -32 + (i * 15);  // Figure 1
		level.powerup_hud[i].y = level.powerup_hud[i].y - 35; 
		level.powerup_hud[i].alpha = 0.8;
		//hud SetShader( shader_inst, 24, 24 );
	}

Figure 1: This line handling width already handles having multiple shaders by multiplying i by 15. When adding a custom powerup you need to increase the amount in the for loop. Ex:

Code Snippet

Plaintext

for(i = 0; i < 3; i++)

This will add a new index for your new shader with the width already properly adjusted.

Spoiler: click to open...

Hmm I know that but, what I'm trying to do is make the shaders in the middle of my screen automatically move depending on how many powerup shaders are active.

The method you said just gives each powerup its own location on the screen and no matter how many powerups are active, the shader will always be in that spot (and it causes some overlapping issues).

Sure I accomplished this method before, but what I'm willing to do is make the shaders adjust depending on how many powerups are active, sort of the way the UGX mod does it for arcade mode (except it doesnt need the transition slide effect like UGX does when you get a second powerup) , where it knows how many powerups are active, and adjust accordingly while still staying towards the center of the screen (I have a total of 6 powerups with shaders).

If i wanted to do this the way WaW does it, there will be ALOT of else if statements that will take a long time to make for every possible powerup combination.

Edit. Solved.
