Beam Extensions

Athena Framework allows modders to create Thing-based beams. (instead of vanilla's mote stream beams)

Your thing's thingClass should be set to BeamRenderer or it's child. It'll also need a BeamExtension mod extension which will hold your beam's parameters.

    public class BeamExtension : DefModExtension
    {
        // Range at which the beam is cut
        public float maxRange;
        // Delay between beam frames
        public int textureChangeDelay;
        // Amount of texture frames
        public int textureFrameAmount = 1;
        // Amount of textures for different beam lengths
        public int sizeTextureAmount = 1;
        // Duration after which beam will be destroyed. Disabled if set to -1
        public int beamDuration = -1;
    }

AF's beams can cycle through multiple textures based both on current tick(like frames) and on beam's current length. Your beam's textures could be set in multiple ways:

When your beam only has one frame and one size texture:

BeamTexPath

Due to how game loads it's assets, it's important that BeamTexPath.png still exists, even if your beam uses frame/size textures.

When your beam has only one size texture but multiple frames:

BeamTexPath
BeamTexPath1
BeamTexPath2
BeamTexPath3

When your beam has only one frame but multiple size textures

BeamTexPath
BeamTexPathA
BeamTexPathB
BeamTexPathC

When your beam has both multiple frames and size textures

BeamTexPath
BeamTexPathA1
BeamTexPathA2
BeamTexPathB1
BeamTexPathB2
